Measurement Commands
Measurement commands control the automated measurement system. The
oscilloscope can display up to four (TDS200) or five (TDS1000, TDS2000,
TDS1000B, TDS2000B, TDS2000C, and TPS2000) automated measurements.
In
the commands, these measurement readouts are named MEAS<x>, where
<x> can be 1, 2, 3, or 4 (or 5 for TDS1000, TDS2000, TDS1000B, TDS2000B,
TDS2000C, and TPS2000).
The best method for taking measurements over the computer interface is to use the
MEASUREMENT:IMMED commands and queries. The immediate measurement
has no front-panel equivalent, and the oscilloscope never displays immediate
measurements.
Because they are computed only w hen they are requested, immediate
measurements slow the waveform update r ate less than displayed measurements .
Use the VALue? query to obtain m easurement results of either displayed or
immediate m easurements.
Several meas urement commands set and query measurement parameters. You
can assign some parame t ers, such as waveform sources, differently for each
measurement readout.
