Boonton 4540 Series RF Power Meter
Operation 4-8
4.5.5 Measure Menu
The Measure menu contains items for controlling measurement acquisition and mode.
Main > Measure > Measurement
Description: Set or return the state of the data acquisition mode for
single or free-run measurements. If Measurement is set
to
On, the 4540 immediately begins taking
measurements (Modulated and Statistical Modes), or
arms its trigger and takes a measurement each time a
trigger occurs (Pulse Mode). If set to Off, the
measurement will begin (or be armed) if the Single
Sweep menu is selected, and will stop once the
measurement criteria (averaging) has been satisfied. If
the measurement mode is set to Modulated or
Statistical, no measurements will be made if
measurement is set to off.
Menu Type: Toggle.
Choices: On, Off
SCPI Command: INITiate:CONTinuous
Main > Measure > Mode
Description: Set or return the system measurement mode. Modulated
mode is a continuous measurement mode primarily for
continuously modulated or CW signals, Pulse mode is a
signal triggered, oscilloscope-like mode that acquires
and analyzes the a pulsed signal as a series of one or
more triggered sweeps, and Statistical mode performs
long-term power distribution analysis on modulated
signals, and may be operated in a start-stop continuous
mode, or a decimated continuous mode.
Note that the measurement mode is global, and affects both channels in a two channel
instrument. If either channel has a CW sensor installed, peak or statistical measurements
will be unavailable in that channel, only the ―primary‖ average power measurement will
be performed.
Menu Type: Selection.
Choices: Pulse, Modulated, Statistical.
