Definitions
6: Frequency/Channel
This parameter specifies the frequency to be generated, either directly (in MHz) or by channel number. If
the radio band specified by the previous parameter is NONE, the present parameter represents the
frequency in MHz; otherwise, the present parameter represents the channel number.
The key path for setting Frequency or Channel from the front panel menus is:
[Source], List Sequencer, List Sequencer Setup, Frequency / Channel
7: Power
This parameter defines the output power level to be generated, in dBm.
The key path for selecting Power from the front panel menus is:
[Source], List Sequencer, List Sequencer Setup, Power
8: Waveform
This parameter specifies the waveform to be generated. The choices are:
•<Waveform>: the name of a waveform file currently in ARB memory. The supported file types are
.wfm, .bin, and .WAVEFORM.
CONT: Continue Previous (that is, continue playback of the waveform from the previous step in the
seequence).
CW: Continuous wave (that is, generate an unmodulated tone).
OFF: Disables RF output of the test set.
NOTE If this parameter is set to CONT, the ARB playback will not pause while the source is
retuning to a new frequency or power level which the step may require.
The key path for selecting the Waveform from the front panel menus is:

9: Step Duration
This parameter, in combination with the following parameter (Time/Count), determines the duration of
the step. The choices are:
TIME: the duration of the step is specified in absolute terms; if this choice is selected, the value of the
Time/Count parameter is interpreted as a duration in ms.
COUNt: the duration of the step is specified as the number of times the waveform file in ARB
memory is played; if this choice is selected, the value of the Time/Count parameter is interpreted as a
a waveform playback count. This choice is applicable only if a waveform file is being played; it
cannot be selected if the step has been set up (by the Waveform parameter) to play a CW tone.
CONTinuous: if this choice is selected, the step will play continuously until the next step starts.
