Error Term Data

The error term descriptions in this section include the following information:
• a table of the error terms
• description and significance of each error term
• measurements affected by each error term
• typical cause of failure for each error term
The same description applies to both the forward (F) and reverse (R) terms.
IMPORTANT Data are listed here as a convenience only. Detailed instrument specifications
are listed in the embedded help in the network analyzer.

Crosstalk
a. The data in this table are uncorrected system performance. The values apply over an environmental temperature
range of 25 °C ±5 °C, with less than 1 °C deviation from the calibration temperature
b. All values for 300 kHz to 10 MHz are typical.
c. All crosstalk values are typical. Measurement conditions: normalized to a thru, measured with two
shorts, 10 Hz IF bandwidth, averaging factor of 8, alternate mode, source power set to the lesser of
the maximum power out or the maximum receiver power.
If Error Terms Seem Worse than Expected
To verify that the system still conforms to specifications, perform a system verification.
