softkey, see Figure 9-4 on page 197 ).
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 page 188 ).
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
page 238
).
RMS When the modulator attenuation setting (see
page 188
) 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
page 215
).
ALC Hold Routing Which marker, if any, implements the ALC hold function (described on
page 205
), 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 page 210 ).
RF Blank Routing Which marker, if any, implements the RF blanking function (described on
page 214
) 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 9-1 on
page 188 ).
BB Freq Offset The baseband frequency offset, in Hz (see
page 241
).
