Not actually pulses, it's a CW measurement
Sorry, my mistake.
How long does the CW signal last, at 101 measurement points?
Long enough for the synthesizers to stabilize, then capture ADC samples of the 5kHz output from the mixer for the receivers. A few milliseconds.
I thought that length would be called a pulse.
(In my Air Force AC&W radar technician days, a 6 millisecond transmission was called a pulse.)
Sure, it's pulsed, but the reason I describe it as CW is that the measurement is not made with looking at the reflection of a transmitted pulse as in a radar.
It's a pulsed CW measurement, and the measurement is made at the same time as the source is on.
The entire sweep is a few hundred milliseconds.
