Boonton 4500B RF Peak Power Analyzer
Remote Operation 5-13
CALCulate:PKHLD
Description:
Set or return the operating mode of the selected channel‘s peak hold function. OFF: instantaneous
peaks are only held for a short time, and then decayed towards the average power at a rate
proportional to the filter time. This is the best setting for most signals, because the peak will
always represent the peak power of the current signal, and the resulting peak-to-average ratio will
be correct shortly after any signal level changes. INST: instantaneous peaks are held until reset by
a new INITiate command. This setting is used to hold the highest peak over a long measurement
interval. AVG: The held peaks correspond to the highest and lowest filtered average power, and
are held until reset. This is useful for monitoring average power fluctuations over a period of
time. In the case of pulse mode, note that all average and peak hold measurements are performed
on the interval between the markers
Syntax: CALCulate[1|2|3|4]:PKHLD
Argument: = {OFF, ON}
Valid Modes: Modulated and Pulse modes
CALCulate:STATe
Description: Set or return the measurement state of the selected channel. When ON, the channel performs
measurements; when OFF, the channel is disabled and no measurements are performed.
Syntax: CALCulate[1|2|3|4|5|6|7]:STATe
Argument: = {ON, OFF}
Valid Modes: Any
CALCulate: SYSTRK
Description: Set or return the state of the system tracking function. When ON, selected parameters of CH 1 and
2, Ext Trig 1 and 2 and Mem 1 and 2 are made to track. Changing either will cause the
corresponding change in all.
