DESCRIPTION
An AC Calibrator is used to check the HP 4934A receiver level accuracy.
EQUIPMENT
AC Calibrator : DATRON 4707A
PROCEDURE
CAUTION Ensure that the AC Calibrator OUTPUT is switched off or set to the minimum level
before proceeding with the following procedure.
1 Connect the AC Calibrator output to the HP 4934A RCV port.
2 Set the HP 4934A as follows:
Measurement : LEVEL FREQ
Receiver (RCV) Impedance : 600Q
Display Mode : RCV
3 Set the AC Calibrator output level to 2.4495 V at 1000 Hz then switch on the
OUTPUT.
4 Check the HP 4934A receiver level reading is between 9.9 and 10.1 dBm.
5 Set the AC Calibrator output level to 77.46 mV.
