HP 16532A - Performance Tests

3-6. DC CAL OUTPUT Test

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

Test Limits:

5.000 V ± 10 mV

Equipment Required:

The following equipment is required for the test.

			Recommended
Equipment Required		Critical Specification	Model/Part Number

Digital Multimeter	0.1 mV resolution, better than 0.005% accuracy		HP 3458A
Cable	50	Ω BNC (m to m) 48-inch	HP 10503A
Adapter	50	Ω BNC (f) to Dual Banana Plug	HP 1251-2277

Procedure:

1.Use the BNC-to-banana adapter to connect the BNC cable between the multimeter and the oscillo- scope module DC CAL OUTPUT connector.

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

	Menu		Selection	Setting

Calibration		Mode		Service Calibration
		Procedure		DC Cal BNC
		DC Volts		0 V

3.The DVM should read close to 0.0000 V. Record the reading to four decimal places.

V1 = __________ .

4.In the Calibration menu set the DC Volts to 5 V.

5.The DVM should read close to 5.0000 V. Record the reading to four decimal places.

V2 = __________ .

6.In the Calibration menu set the DC Volts to 0 V.

7.Subtract V1 from V2. The difference should be between 4.990 and 5.010 V. Record the reading in the performance test record.
