17.5.2 FRA Actions
FRA Actions
Once you have setup the FRA Control Panel, click Start Sweep to begin the
capture process. If you have Auto Sweep Amplitude, or Auto Setup selected,
the Start Sweep will initiate measurement of the current environment,
before actually starting the sweep - you can see the current state in
. You can clear the Spectrum Display by clicking Clear
Spectra. The current frequency is displayed, and you can over-type this to
change the Signal Generator frequency if you want.
17.5.3 Signal Generator Control
Use this panel to setup the FRA frequency range, amplitude, offset and
sweep method. These controls work in parallel with the Signal Generator
Control Panel.
the start of the sweep frequency range.
the completion of the sweep frequency range.
If the ratio between Stop Frequency and Bandwidth is > 500 000, then the
actual stop frequency will be reduced.
the default Signal Generator output amplitude in V p-p.
See the Sweep Amplitude Control below on how this might be varied.
the DC voltage by which the Signal Generator is Offset.
If using an electrolytic capacitor use a value of 0 - 1V. You can also use this
to offset a power supply up to 3.6V for live power plane impedance testing.
sets the number of frequency steps per decade. If Log Sweep is on, these
are spread logarithmically, otherwise linearly.
sweeps once or repeatedly from the start frequency up to the stop
frequency.
sets how the amplitude will vary with frequency:
Constant, the Sig Gen Amplitude is set by Sig Gen Amp.
Auto, the system measures the gain of the Device Under Test at selected
frequencies, , and then carries out the sweep, varying the amplitude
