Using the MEASURE Menu Keys
Overview of the MEASURE Menus
The measurement function menus are divided into three categories:
• Frequency measurements on channel 1, 2, or 3 (optional) and ratio of
frequencies between channels.
• Time interval, period, and pulse characterization measurements.
(The HP 53131A/132A provides one key-press operation for such pulse
measurements as risetime, falltime, pulse width, etc., which have
traditionally required multiple key presses or operations.)
• Other measurements (dutycycle, phase, peak voltage, and totalize).
To sequence through the menus of the MEASUREment function keys
(Freq & Ratio, Time & Period, and Other Meas keys), you simply need
to repeatedly press the appropriate MEASURE key to cycle through (and
loop around) the menus under the key. Each press of a MEASURE key
will advance the Counter to the next measurement function in the menu.
NOTE The menus under the MEASURE keys will terminate (select function and
return to measurement result display) after two seconds.
