Press Save Setup To Header .
Both the Saved Header Settings column and the Current Inst. Settings column now display
the same settings; the Saved Header Settings column lists the settings saved in the file header.
The file header contains the following signal generator settings:
32–Character 
Description:
A description entered for the header, such as a the waveform’s function (saved/edited with the Edit
Description key, see Figure 3- 2 on page 83 ).
Sample Rate: The ARB sample clock rate.
Runtime Scaling: The Runtime scaling value. Runtime scaling is applied in real–time while the waveform is playing.
This setting can be changed only for files in the dual ARB player.
Marker 1...4 Polarity: The marker polarity, positive or negative (described on page 111 ).
ALC Hold Routing: Which marker, if any, implements the PSG’s ALC hold function (described on page 98 ).
RF Blank Routing: Which marker, if any, implements the PSG’s RF blanking function (described on page 109 ).
I/Q Mod Filter: The I/Q modulator filter setting. The modulator filter affects the I/Q signal modulated onto the RF
carrier.
I/Q Output Filter: The I/Q output filter setting. The I/Q output filter is used for I/Q signals routed to the rear panel
I and Q outputs.
Mod Attenuation: The I/Q modulator attenuation setting.
