Making Complex Measurements

Making Stimulus Response Measurements

Measurements are made continuously, updating at the end of each sweep. This allows you to make adjustments and see changes as they happen. The single sweep mode can also be used, providing time to study or record the data.

The N dB bandwidth measurement error is typically ± 1% of the span.

Example:

Measure the 3 dB bandwidth of a 200 MHz bandpass filter.

1.To measure the rejection of a bandpass filter, connect the equipment as shown in Figure 2-5. This example uses a 200 MHz bandpass filter.

	2.	Perform a factory preset by pressing Preset, Factory Preset (if
		present).
	3.	Set the Y-Axis Units to dBm by pressing AMPLITUDE, More,
		Y-Axis Units, dBm.
	4.	Set the span to 100 MHz by pressing SPAN, Span, 100, MHz.
	5.	Set the center frequency to 200 MHz by pressing FREQUENCY,
		Center Freq, 200, MHz.
	6.	Set the resolution bandwidth to 10 kHz by pressing BW/Avg, Res BW,
		10, kHz.
	7.	Turn on the tracking generator and if necessary, set the output
		power to –10 dBm by pressing Source, Amplitude (On), –10, dBm.
	Excessive signal input may damage the DUT. Do not exceed the
CAUTION
	maximum power that the device under test can tolerate.
