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.
