Measurement speed
Measurement time for 201 measurements points, with
200 MHz span, 300 kHz measurement
bandwidth with 900 MHz center frequency < 8 ms
Measurement time per point 300 kHz measurement bandwidth,
CW mode < 4 us
Time for measurement and data transfer for 201 measurements points, with
800 MHz start frequency, 1 GHz stop
frequency, 300 kHz measurement
bandwidth (No additional time for data
transfer is needed, as this occurs
simultaneously during the measurement.) typ. 8 ms
Switching time between channels with no more than 2001 points < 5 ms
Switching time between two preloaded
instrument settings with no more than 2001 points < 5 ms
