Description Item
Displays the current control mode. Active Mode
Selects the type of command: Command Type
Cyclic—The function cycles at the specified amplitude and
frequency.
Sweep—The function sweeps the command signal between the
specified frequency limits at the rate specified.
Random—The function sweeps randomly according to the RMS
amplitude and frequency limits you specify.
Descriptions of each command type follow this table.
Specifies the setpoint that the signal’s amplitude centers on. Target Setpoint
The initial ramp time to the Target Setpoint is specified as a
command option (Tools menu > Channel Options > Channel Options
window > Command Options tab > Setpoint/Span Times > Setpoint).
Target Setpoint ramp times are proportional to the full scale. If the
value has less distance to travel, the execution time will be
correspondingly less than the specified time.
Displays for a Command Type of Cyclic and Sweep. Amplitude (±)
Specifies the signal’s amplitude. The specified amplitude applies
equally to both sides of the Target Setpoint.
Displays for a Command Type of Random. RMS Amplitude (±)
Specifies the signal’s RMS amplitude.
RMS (Root Mean Square) amplitude is always smaller than peak
amplitude. The maximum display range of the RMS amplitude is
set to 20% full-scale.
Displays for a Command Type of Cyclic and Sweep. Frequency
Specifies the signal’s frequency.
The maximum frequency is limited to 20% of the high system clock
rate.
During a Sweep, this control’s pointer tracks the sweep frequency.
Displays for a Command Type of Random. Frequency Min/Max
Sets the minimum and maximum frequencies of the random signal.
Click on the label to view the allowable minimum and maximum
limits.
These controls display for a Command Type of Sweep. Sweep
Defines the signal’s sweep.
