Examples

MEASUREMENT:IMMED:UNITS? might return "s", indicating that the unit for the

immediate meas urement is seconds.

MEASUrement:IMMed:VALue? (Query Only)

Executes the immediate oscilloscope measurement speciﬁed by the

MEASUrement:IMMed:TYPe command. The measurement is taken on the

source speciﬁed by the MEASUrement:IMMed:SOUrce command. Immediate

queries and commands are the preferred measurement method for programming.

To check whether the measurement was successful, use the *ESR? query followed

by the EVENT? or ALLEv? queries to read the Standard Event Status Register

(SESR).

NOTE. If the channel speciﬁed by MEASUrement:IMMed:SOUrce is not currently

displayed, the oscilloscope generates event 2225 and returns 9.9E37.

If Trigger View is active, Scan mode is in effect, or the display format is set to XY,

this query returns 9.9E37 and generates event 221 (Settings conﬂict)

When math is FFT, tur ned on, and used as a measurement source, attem pting to

query the measurement value returns 9.9e37 and raises error 2225 (no waveform

to measure).
