R648 (Channel 2 only) is switched between TS-2 and the Column output line when the CH 2 POLARITY switch is in the INVERT position . - This results in the symbol I (inverted) being displayed preceding the deflection factor readout .
Switching resistors are used to indicate the setting of the VOLTS/DIV switch to the mainframe readout system . I - he VOLTS/DIV switch is a cam-type switch . The dots on the contact-closure chart (see Diagram 6) indicate when the associated contacts are closed . R633, R634, and R635 select the number 1, 2, or 5 depending on the resistor combination that is switched in . R637 selects the m (milli-) prefix and R639 selects the symbol V (volts) in the 5 mV through .5 V (500 mV) positions of the VOLTS/DIV switch . R638 selects the symbol V in the 1, 2, and 5 V positions . R630, R631, and the output of the probe sensing stage (Q620) select the decimal point (number of zeroes) again depending on the resistor combination switched in by the VOLTS/DIV switch . Fig. 3-4. Input/Outpu t combinations for DISPLAY MODE and TRIGGER SOURCE switch selections .
CONNECTORS AND READOUT General The Connectors and Readout circuit consists of the power supply and signal distribution from the Interface Connector and the Readout Encoding circuit . A schematic of this circuit is shown on Diagram 6 in the Diagrams section .
Connectors All the connections made to the mainframe by the 7A18 are shown on the Connectors portion of Diagram 6 . Also shown are the power supply decoupling components .
REV . D, JAN . 1975
Probe sensing stage Q620 identifies the attenuation factor of the probe connected to the input connector by sensing the amount of current flowing from the current sink through the probe coding resistance . The output of this circuit corrects the mainframe readout system to include the probe attenuation factor . The third contact of the input connector provides the input to the probe sensing stage from the probe coding resistance (coded probes only ; see Operating Instructions) . The third contact is also used for the IDENTIFY input . The coding resistor forms a voltage divider with R621 through CR621 to the --15 V supply . The resultant voltage sets the bias on Q620 and determines, along with emitter resistor R622, the collector current . When the -15 volt time-slot pulse is applied to Interface Connector B33, Q620 is interrogated and its collector current is added to the column current output through Interface Connector A37 .

Circuit Description-7A18/7A18N With a 1X probe (or no probe) connected to the input connector, 0620 is turned off . The deflection factor readout is determined by the VOLTS/DIV switch position . With a 10X probe connected, the bias on Q620 will allow 100 microamperes of collector current to flow . This increases the deflection factor readout by a factor of 10 . The IDENTIFY button (S13 or S23 on Diagram 1) does two things when pressed : 1 . It causes the trace representing the appropriate channel of the 7A18 to move about 0 .3 division (see the discussion on the Channel 1 or Channel 2 Input Amplifier) .
2 . Forward biases CR621 and Q620 to result in a sufficient amount of collector current which, when added to the column current output, replaces the deflection factor readout with the word "IDENTIFY" . These two actions aid in identifying the 7A18 trace when multiple traces are displayed . When the IDENTIFY button is released, the deflection factor readout and trace position are restored .
For further information on the operation of the readout system, see the oscilloscope instruction manual .

The insulated wires used for interconnection in the 7A18 are color coded to facilitate tracing a wire from one point to another in the unit . Semiconductor Lead Configuration . Fig . 4-1 shows the lead configuration of the semiconductor devices used in this instrument .
2 . DC Voltmeter and Ohmmeter--A voltmeter for checking voltages within the circuit and an ohmmeter for checking resistors and diodes are required . 3 . Test Oscilloscope--A test oscilloscope is required to view waveforms at different points in the circuit . A Tektronix 7000-series Oscilloscope equipped with a readout system, 7D13 Digital Multimeter unit, 7B-series Time-Base unit, and a 7A-series Amplifier unit with a 10X probe will meet the needs for items 2 and 3 .
Troubleshooting Procedure Troubleshooting Equipment The following equipment is useful for troubleshooting the 7A18 . 1 . Semiconductor Tester---Some means of testing the transistors, diodes, and FET's used in this instrument is helpful . A transistor-curve tracer such as the Tektronix Type 576 will give the most complete information .
This troubleshooting procedure is arranged in an order which checks the simple trouble possibilities before proceeding with extensive troubleshooting . 1 . Check Control Setting . An incorrect setting of the 7A18 controls can indicate a trouble that does not exist .

2. Check Associated Equipment. Before proceeding with troubleshooting of the 7A18, check that the equipment used with this instrument is operating correctly. If possible, substitute an amplifier unit known to be operating correctly into the indicator unit and see if the problem persists . Check that the inputs are properly connected and that the interconnecting cables are not defective. 3. Visual Check. Visually check the portion of the instrument in which the trouble is suspected . Many troubles can be located by visual indications, such as unsoldered connections, broken wires, damaged circuit boards, damaged components, etc. 4. Check Instrument Performance. Check the calibration of the unit, or the affected circuit by performing Part I -- Performance Check of Section 5. The apparent trouble may only be a result of misadjustment and may be corrected by calibration . Complete calibration instructions are given in Part I I of Section 5 .
5. Check Voltages and Waveforms. Often the defective component or stage can be located by checking for the correct voltage or waveform in the circuit. Typical voltages and waveforms are given on the diagrams ; however, these are not absolute and may vary slightly between instruments. To obtain operating conditions similar to those used to take these readings, see the instructions in the Diagrams section . 6 . Check Individual Components . The following methods are provided for checking the individual components in the 7A18 . Components which are soldered in place are best checked by disconnecting one end to isolate the measurement from the effects of surrounding circuitry .
A. TRANSISTORS AND INTEGRATED CIRCUITS . The best check of transistor and integrated circuit operation is actual performance under operating conditions. If a transistor or integrated circuit is suspected of being defective, it can best be checked by substituting a component known to be good ; however, be sure that circuit conditions are not such that a replacement might also be damaged. If substitute transistors are not available, use a dynamic tester (such as Tektronix Type 576) . Static-type testers may be used, but since they do not check operation under simulated operating conditions some defects may go unnoticed. Fig. 4-1 shows base pin and socket arrangements of semiconductor devices. Be sure the power is off before attempting to remove or replace any transistor or integrated circuit.
REV . D, MAY, 1975
Integrated circuits can be checked with a voltmeter, test oscilloscope, or by direct substitution . A good understanding of the circuit description is essential to troubleshooting circuits using integrated circuits . Use care when checking voltages and waveforms around the integrated circuits so that adjacent leads are not shorted together . An integrated-circuit test clip provides a convenient means of clipping a test probe to the 14- and 16-pin integrated circuits. This device also doubles as an integrated-circuit extraction tool . B. DIODES . A diode can be checked for an open or for a short circuit by measuring the resistance between terminals with an ohmmeter set to the R X 1 k scale . The diode resistance should be very high in one direction and very low when the meter leads are reversed . Do not check tunnel diodes or back diodes with an ohmmeter .
Do not use an ohmmeter scale that has a high internal current. High currents may damage the diodes .
C . RESISTORS. Check resistors with an ohmmeter . Resistor tolerance is given in the Electrical Parts List . Resistors normally do not need to be replaced unless the measured value varies widely from the specified value. D. CAPACITORS . A leaky or shorted capacitor can be detected by checking resistance with an ohmmeter on the highest scale. Use an ohmmeter which will not exceed the voltage rating of the capacitor. The resistance reading should be high after initial charge of the capacitor. An open capacitor can best be detected with a capacitance meter, or by checking whether the capacitor passes AC signals. 7 . Repair and Readjust the Circuit. Special techniques required to replace components in this unit are given under Component Replacement. Be sure to check the performance of any circuit that has been repaired or that has had any electrical components replaced . Recalibration of the affected circuit may be necessary .

OPTION 6-7A18
Fig . A . 7A18 OPTION 6.
The 7A18 with Option 6 is equipped with added DC offset circuits that provide up to ±200 divisions of baseline offset within the input dynamic range, with uncalibrated front panel variable controls for each channel .
DC OFFSET . The internal DC Balance circuits have been modified to provide up to ±1 V DC offset directly to the input of each amplifier, which gives up to ±200 divisions of baseline offset range for all VOLTS/DIV settings .
CONTROLS . Separate CH 1 and CH 2 (uncalibrated) Variable Offset controls are added to the front panel . Each input coupling selector switch has an additional position for the DC offset function . The variable controls are concentric with the position controls, replacing the IDENTIFY pushbuttons formerly used on the unmodified unit .
APPLICATION . The added Offset facility should be used only for offsetting a DC level in the waveform to be observed . Amplifier characteristics are not suitable for use of this feature for "slideback" type measurements of peak or peak-to-peak high-frequency or pulse waveforms exceeding 15 divisions peakto-peak amplitude .
OPTION 6----7A18
CHARACTERISTICS AMPLIFIER LINEAR OFFSET RANGE. Common-mode DC range of the input amplifiers is sufficient to provide linear amplification of signals within normal 7A18 performance specifications at offsets of up to P200 divisions . EFFECTIVE VOLTAGE OFFSET . Effective voltage offset values for calibrated VOLTS/DIV steps areas follows (VARIABLE control in Cal position) : EFFECTIVE OFFSET RANGE VOLTS/DIV

'Maximum input rating 250 V when direct coupled. Full offset range should not be used above 1 V/DIV. `Maximum input rating of most probes is 500 ----600 V. Full offset range should not be used at VOLTS/DIV settings above .2 with 10X probe.
CALIBRATION CALIBRATION . Perform the following steps for checking Channel 1 and 2 OFFSET Range: a . Reset the Input coupling to GND and the VOLTS/DIV to 5 mV and position the trace to the center horizontal graticule line . b . Set the standard amplitude calibratof for one-volt +DC output and set the input coupling switch to DC OFFSET . c . CHECK---Using the OFFSET control, check that the trace can be returned to graticule center . d . Set the standard amplitude calibrator for a minus (--) one-volt DC output . e . CHECK--Using the OFFSET control, check that the trace can be returned to graticule center . CIRCUIT DESCRIPTION. DC levels of up to +200 divisions can be offset by switching the input coupling to DC OFFSET and using the OFFSET control . . In the DC OFFSET mode, the selected offset voltage from OFFSET - control R12 (R22, CH 2), is applied to the base of 0320 (Q520, CH 2) through current-limiting resistor R320 (R520, CH 2) . This additional bias voltage is used to balance the differential input of 0220 (Q420, CH 2) . LED's are inserted in series with both CR220 and CR221 (CR420, CR421, CH 2) to allow a larger voltage swing at the base of Q220 (Q420, CH 2) . The schematics of the Option 6 circuits are shown on diagrams 1, 2 and 3.
