ASK:BAUD <rate>(?)
HS Syntax: 0066A<float>(?)
Description
This allows the user to select ASK word rate. The word rate is the interval of which the bit streams in the
ASK data array are clocked causing the output amplitude to hop from one level to shifted amplitude level
values and vice-versa.

Description
<rate>
1 to 10e6 Numeric
10e3
Programs the rate at which the frequency shifts from
carrier to the shifted frequency in units of Hz.
Response
The 3152B returns the current baud value.
ASK:FREQuency:MARKer <index>(?)
HS Syntax: 0068A<integer>(?)
Description
Programs where in the data stream the 3152B generates a pulse designated as an ASK marker or index
point. The marker pulse is generated at the SYNC output connector. Note that if you intend to program the
marker position, you must do it before you load the ASK data list.

Description
<index>
1 to 1000 Numeric
(integer only)
1
Programs a marker pulse at an index bit position.
Response
The 3152B returns the current marker position.
ASK:DATA <ask_data>
HS Syntax: 00671#<string>(?)
Description
Loads the data stream that will cause the 3152B to hop from one amplitude level to a shifted amplitude level
and vice-versa. Data format is a string of "0" and "1" which define when the output generates the base level
and when it shifts amplitude to the ASK value. A "0" specifies the base level amplitude and a "1" specifies a
shifted amplitude level. Note that if you intend to program marker position, you must do it before you load the
ASK data list.
Below you can see how an ASK data table is constructed. The sample below shows a list of 10 shifts. The
3152B will step through this list, outputting either the base or shifted amplitudes, depending on the data list: A
Zero will generate the base level and a One will generate the shifted amplitude. Note that the waveform is
always a sine wave and that the last cycle is always completed.

and vice-versa.
