Measurement uncertainty

See table below

Test level of –3 dBm
No averaging
Bandwidth 10 Hz
Ambient temperature equal to the calibration temperature.
A 12 error term calibration is assumed carried out with a good quality 3.5 mm calibration kit capable of achieving the performance specified.

Spurious responses

–76 dBc typical, –70 dBc max.

The main spurious response occurs at close to (2 x RF + 1.3) MHz, where RF is the test frequency in MHz. For example, when testing a bandpass filter with a centre frequency of, say 1900 MHz, an unwanted response will occur around 949.35 MHz. There may also be spurious responses close to (3 x RF + 2.6) MHz. In all known cases the levels will be as stated.
