DESCRIPTION
An AC Calibrator is used to verify the Low, Mid and High impulse noise
thresholds.
EQUIPMENT
AC Calibrator : DATRON4707A
CAUTION Ensure that the AC Calibrator OUTPUT is switched olf or set to the minimum level
before proceeding with the following procedure.
PROCEDURE
1 Connect the AC Calibrator output to the HP 4934A RCV input.
2 Set the AC Calibrator output level to 1.732 mV at 1000 Hz then switch on the
OUTPUT.
