    Spurious responses –76 dBc typical, –70 dBc max.   The main spurious response occurs at close to (2 x RF + 1.3) or (3 x RF + 2.6) 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 632.47 or 949.35 MHz. In all known cases the levels will be as stated.

    • Test level of -3 dBm.

    • Bandwidth 10 Hz.
    • Ambient temperature equal to the calibration temperature.

    A 12 error term calibration is assumed carried out with a good quality SMA or PC3.5 mm calibration kit capable of achieving the performance specified.

    10 MHz to 6 GHz or 8.5 GHz, 201-point trace length. For other lengths and bandwidths, sweep time is approximately:
    TSWP (s)= N x (TMIN + FBW / RBW) + TARM
    where N = number of frequency points,
    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).
    For sweep repetition period add software rearm time:
    TARM = average 6.5 ms or worst case 50 ms. For markers on, increase TARM by 39 ms.
