Table 8-1 File Header Entries
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).
Sample Rate The waveform playback rate. This is the ARB sample clock rate, set in the Arb Setup menu (shown
in Figure 8- 1 on page 147).
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 197).
RMS When the modulator attenuation setting (see page 147) 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 174).
ALC Hold Routing Which marker, if any, implements the ALC hold function (described on page 163), 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 168).
