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.

TSWP (s)= N x (TMIN + FBW / RBW) + TARM

TMIN (s)= minimum time per point (s2p: 167 μs; s1p: 85 μs),
FBW = bandwidth settle factor (s2p: 1.91; s1p: 0.956),
RBW = resolution bandwidth (Hz).
