32–Character
Description
A description entered for the header, such as a the waveform’s function (saved/edited with the
Edit Description softkey, see Figure 8-4 on page163).
Sample Rate The waveform playback rate. This is the ARB sample clock rate, set in the Arb Setup menu (shown
in “Dual ARB Softkeys” on page154).
Runtime Scaling The Runtime scaling value is applied in real–time while the waveform is playing. This setting can be
changed only for files playing in the dual ARB player (see
page204).
RMS When the modulator attenuation setting (see
page154) is set to Auto, this value is used to calculate
the I/Q modulator attenuation setting to optimize ACPR. Value: 0 to 1.414213562.
Marker 1...4 Polarity Marker polarity can be positive or negative (described on
page181).
ALC Hold Routing Which marker, if any, implements the ALC hold function (described on
page171), which holds the
ALC at its current level when the marker signal is low. All waveforms generated in the signal
generator have a marker on the first sample point. To see the results from the three routing
selections, you may need to select a range of sample (marker) points (see “Setting Marker
Points in a Waveform Segment” on page176).
RF Blank Routing Which marker, if any, implements the RF blanking function (described on page180) when the
marker signal is low. RF blanking also uses ALC hold. There is no need to select the ALC Hold
Routing for the same marker when you are using the RF Blank Routing function. When the marker
signal goes high, RF blanking discontinues.
Mod Attenuation The I/Q modulator attenuation setting (set in the Arb Setup menu shown in Figure 8-1 on
page154).
BB Freq Offset The baseband frequency offset, in Hz (see
page207).
