HP 16532A - Performance Tests

3-11. BANDWIDTH

This test checks the bandwidth of the oscilloscope module.

Specification:

Bandwidth (dc coupled) dc to 250 MHz

Equipment Required:

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

			Recommended
Equipment Required		Critical Specification	Model/Part Number

Signal Generator	1	- 250 MHz at approx 170 mVrms	HP 8656B
Power Meter/Sensor	1	- 250 MHz ± 3% accuracy	HP 436/8482A
Power Splitter	Outputs differ by < 0.15 dB		HP 11667B
Cable	Type N (m to m) 24-inch		HP 11500B
Adapter	50 Ω Type N (m) to BNC (m)		HP 1250-0082

Procedure:

1.With the N cable, connect the signal generator to the power splitter input. Connect the power sensor to one output of the power splitter.

2.Using an N-to-BNC adapter, connect the other power splitter output to the Channel 1 input of the oscilloscope module.

3.In the Waveform Selection menu delete channel 2. If channel 1 is not inserted, insert channel 1. Set the following parameters.
