HP 16532A - Performance Tests

3-10. OFFSET ACCURACY

This test verifies the offset accuracy.

Specification:

± (1.0% of channel offset + 2.0% of full scale)

Equipment Required:

The following equipment is required for the test. Procedures are based on the model or part numbers rec- ommended.

			Recommended
Equipment Required		Critical Specification	Model/Part Number

DC Power Supply	− 35.000 to + 35.000 Vdc, ± 1 mV resolution		HP 6114A
Digital Multimeter	Better than 0.1% 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:

Zero-Input Offset

1.Disconnect all cables and probes from the oscilloscope inputs. In the Waveform Selection menu de- lete channel 2. If channel 1 is not inserted, insert channel 1. Then set up the oscilloscope module according to the following parameters in the order given:

	Menu		Selection	Setting

Channel		Input		1
		Probe		1:1
		v/Div		4 V
		Offset		0 V
		Coupling		1 MΩ / DC
		s/Div		500 ns
Trigger		Mode		Immediate
Display		Mode		Average
		Average #		32
		Grid		On
		Markers		On

2.With the DC power supply disconnected from the channel input, make sure the markers are near the center of the display.
