HP 16532A - Performance Tests

3-7. AC CAL OUTPUT Test

The AC CAL OUTPUT port on the rear panel is used for instrument calibration and probe compensation. Though calibrator accuracy is not specified in the performance specifications, it must be within limits in or- der to provide accurate calibration.

Test Limits:

1000 Hz ± 10%, 0.8 Vp_p ± 10%

Equipment Required:

The following equipment is required for the test.

		Recommended
Equipment Required	Critical Specification	Model/Part Number

Cable	50 Ω BNC (m to m) 48-inch	HP 10503A

Procedure:

1.Use the BNC cable to connect the AC CAL OUTPUT to channel 1 input of the oscilloscope module.

2.On the oscilloscope module set the following parameters in the order given:

	Menu		Selection	Setting

Calibration		Mode		Service Calibration
		Procedure		Oscillator Output
		Signal		Probe Compensation
Channel		Coupling		1 MΩ/DC
		Probe		1:1

3.In the Calibration menu select AUTOSCALE.

4.In the Auto-Measure menu verify that the waveform is approximately 0.8 Vp_p at approximately 1000 Hz. Record the reading in the performance test record.
