Pass/Fail Limit (Specification) Descriptions

6. RXA Expandor Zero Reference Level (dBV)

This sets the pass/fail limits used when the expandor’s output voltage

at the 0 dB reference level is measured. Upper and lower limits must be

entered in dBV rms.

Pass/fail limits are determined by using any applicable standard, such

as:

• MSUT Specification

The test is performed and pass/fail limits are available so that the

operator can measure the RXA Expandor Zero Reference Level and

compare the result to specifications that meet his or her needs.

If the operator does not wish to compare the measurement results to

specifications, the “check” setting for pass/fail limit 15. TXA

Compressor Tracking Error >0dB (dB) can be set to “none.” See “To

Change Pass/Fail Limits” in the

Agilent Technologies 83217A Test

Software User’s Guide.

Example

If you desire the output voltage from the receiver to be −20 dBV rms ±1

dB, enter

−21 as the Lower Limit and −19 as the Upper Limit.
