Chapter 4, Test, Parameter, and Pass/Fail Limit Descriptions
Pass/Fail Limit 18, RX Variation of Sens Delta Frequency
Pass/Fail Limit 18, RX Variation of Sens Delta Frequency
This sets the pass/fail limits for testing the variation of sensitivity with signal
frequency, which is the change of input signal level required to maintain the
standard signal-to-noise ratio (the usable sensitivity SINAD level) as a function of
the signal frequency.
Pass/Fail limits are determined from an applicable industry standard, such as:
• Industry standard: EIA/TIA-204-D, Section 8.0, Variation of Sensitivity with Signal
Frequency
For Example:
If your specified receiver frequency stability should not be greater than 1.5 kHz to
maintain the standard SINAD level, enter
1.5 in the lower-limit column and 0 in
the upper-limit column. Limits are entered in kHz.
It’s Used in the Following Test:
