Performance Check Procedure
m. Select PK-PK from the VOLTMETER menu and set CH 2 INVERT off.
n, CHECK—the readout Is between 46.5 mV and 53.5 mV.
o. Disconnect calibration generator.
4. 25 MHz +Peak, - Peak, and Peak-to-Peak Volts
Accuracy
a. Connect leveled sine-wave generator (SG 503) output to the CH 2
Input via a 50 BNC coaxial cable and a 50 1 BNC termination.

+0.5 mV at 50 kHz.
d. © Set leveled sine-wave generator output for 25 MHz.
e. CHECK—the readout Is between 95.0 mV and 105.0 mV.
f. Select -PEAK from the VOLTMETER menu.
g. CHECK—the readout is between -46.0 mV and -54.0 mV.
h. Select +PEAK from the VOLTMETER menu.
|. CHECK—the readout Is between 46.0 mV and 54.0 mV.
5. 100 MHz +Peak, -Peak, and Peak-to-Peak
Volts Accuracy
a. Set leveled sine-wave generator (SG 503) output frequency to
100 MHz.
