This manual explains examples of the Capture & Playback Function using the Signal Analyzer MS2690A
series (MS269xA hereafter) and the MS2830A and MS2840A with installed Vector Signal Generator
option.
When using the Capture & Playback function, the RF signal captured using the signal analyzer
to generate an IQ data file (capture hereafter) for generating the waveform pattern using the built-in
vector signal generator
For example, it is better to use the Capture & Playback function to generate RF signals from playback
from the captured data in the following cases:
 Although we want to evaluate actual wireless equipment signals, it is difficult to create and
playback waveforms using general-purpose signal generators and software.
 When using wireless equipment (golden unit hereafter) as a signal source, fine adjustment of
the output level is difficult and the output is unstable.
 If many golden units (e.g. base stations) are required, the cost is much higher than using a
measuring instrument.
Since this function automatically calculates the average power (rms) when generating the waveform
pattern, the output level set at the signal generator after generation equals the average power.
