10 MHz to 6 or 8.5 GHz, 201-point trace length. For other

lengths and bandwidths the sweep time is approximately:

T

SWP(s) = N × (TMIN + FBW / RBW)

where:

N

= number of frequency points

T

MIN(s) = minimum time / point (s2p: 167 µs; s1p: 85 µs)

F

BW

= bandwidth settle factor (s2p: 1.91; s1p: 0.956)

R

BW

= resolution bandwidth (Hz)

For sweep repetition period, add software rearm time:

T

ARM 

= average 6.5 ms or worst case 50 ms

For markers on, increase T

ARM by 39 ms
