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. |

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.
