2. Set the HP 8656A to output a 20 MHz sinewaveat 15 mV rms.lncrease the frequency of the HP
8656A and verify the counter displays the proper frequency from 20 MHzto 100 MHz. Record
the results on the test card (Pass/Fail).
Ill. CHANNEL B FREQUENCY RESPONSE AND SENSITIVITY TEST FOR HP 5384A
Description:
A signal generator with a calibrated output is set to the specified HP 5384A channel B minimum signal
sensitivity
level. The frequency is slowly increased from 50 MHz up to 225 MHz at a constant level, and
the HP 5384A reading is checked for the proper count.
