Pass/Fail Limit (Specification) Descriptions

4. RXA Expandor Tracking Error <0dB (dB)

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

measured at input levels below the 0 dB reference level. The output

voltage tolerance should be within the pass/fail limits. Lower and

Upper Limits must be entered in dB.

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

as:

• EIA/TIA Standard: Expandor

Example

If you desire the output voltage tolerance below the 0 dB reference level

to be

±2 dB, enter −2 as the Lower Limit and 2 as the Upper Limit.
