Multitone Subsystem–N5172B/82B ([:SOURce]:RADio:MTONe:ARB)
The marker signal has a minimum of a two–sample delay in its response relative to the waveform
signal response. To compensate for the marker signal delay, offset marker points from the waveform
sample point at which you want the ALC sampling to begin.
The ALC hold setting is part of the file header information, so saving the setting to the file header
saves the current marker routing for the waveform file.
NOTE A waveform file that has unspecified settings in the file header uses the previous waveform’s
routing settings.
For more information on the marker ALC hold function, see the User’s Guide.
NONE This terminates the marker ALC hold function.
M1–M4 These are the marker choices. The ALC hold feature uses only one marker at a
time.
*RST NONE
:MDEStination:PULSe
Supported N5172B/82B
CAUTION The pulse function incorporates ALC hold. Incorrect automatic level control (ALC)
sampling can create a sudden unleveled condition that may create a spike in the RF
output potentially damaging a DUT or connected instrument. Ensure that you set
markers to let the ALC sample over an amplitude that accounts for the high power levels
within the signal.

This command enables the marker pulse/RF blanking function for the selected marker.
This function automatically incorporates the ALC hold function, so there is no need to select both the
ALC hold and pulse/RF blanking functions for the same marker.
NOTE Do not use ALC hold for more than 100 ms, because it can affect the waveform’s output
amplitude.
The signal generator blanks the RF output when the marker signal goes low. The marker polarity
determines when the marker signal is low. For a positive polarity, this is during the marker points.
For a negative polarity, this is when there are no marker points. For setting a marker’s polarity, see
“:MPOLarity:MARKer1|2|3|4” on page 315.
NOTE Set marker points prior to using this function. Enabling this function without setting marker
points may create a continuous low or high marker signal, depending on the marker polarity.
This causes either no RF output or a continuous RF output. For setting the marker points,
see “:MARKer[:SET]” on page 283.
