Measurement Commands
Measurement commands control the automated measurement system.
Table 2--20 on page 2--28 lists these commands.
Up to four automated measurements can be displayed on the screen. In the
commands, these four measurement readouts are named MEAS<x>,where<x> can
be 1, 2, 3,or4.
In addition to the four displayed measurements, the measurement commands let
you specify a fifth measurement, IMMed. The immediate measurement has no
front-panel equivalent. Immediate measurements are never displayed, but return
the immediate value of the specified measurement. Because they are computed
only when needed, immediate measurements slow the waveform update rate less
than displayed measurements.
Whether you use displayed or immediate measurements, you use the VALue?
query to obtain measurement results.
Measurement commands can set and query measurement parameters. You can
assign some parameters, such as waveform sources, dif ferently for each
measurement readout. Other parameters, such as reference levels, have only one
value, which applies to all measurements.
