c. Set Model 410C FUNCTION SELECTOR to +DCV ; RANGE to .015 V.
d. Adjust voltmeter calibrator for +. 015 VDC output.
e. The dc voltmeter should read +1.5 v. This will vertfy a gain of 100, when the gain /A/ equals E DC out/E 410C.
a. Leave the dc voltmeter connected to the DC AMPLIFIER OUTPUT as in Paragraph
b. Set the Model 410C RANGE to 1500 V; FUNCTION SELECTOR to +DCV.
c. Short the Model 410C DCV and COM cables.
Note dc voltmeter readings. This reading should be less than 7 . 5 millivolts .
d. Reset Model 410C RANGE to 1.5 V. DC Voltmeter should read less than 7.5 mv.
CHECK.
a. Connect an external DC Voltmeter Model 3440A/3442A) to Model 410C DC AMPLIFIER OUTPUT terminals on rear panel.
b. Set Model 410C FUNCTION SELECTOR to OHMS position.
c . Record voltage indicated on external dc voltmeter for use as a reference.
d. Connect a 1.5 k ohm ±1% resistor Part No.
a. Figure
required for this operation. Do not place Model 410C AC Probe in
b. Adjust signal generator for a 0.7 volt (rms) output at 1000 cps.
c. Connect Model 11036A AC Probe to signal generator and read output on Model 410C Voltmeter (meter should read 0.7 volts).
d. Remove probe tip from Model 11036A and connect the ac probe as shown in Figure
e. Turn signal generator to 50 Mc and adjust signal generator for a power reading of 9.8 dbm (0.7 volts) on the power meter.
f. The difference between reading on Model 410C meter and 0.7 volt reference is the ac probe error at that frequency.
g. Repeat steps f and g every 100 Mc from 50 to 700 Mc.
