Time to receive measured values is different for the :FETCh? and:READ? commands.
See: "9.8 Data Exporting Methods" (p. 148)
Reading the Most Recent Measurement
Syntax
Query
:FETCh?
Description
Reads the most recent measurement. No trigger occurs.
See: "Measurement Value Formats" (p. 140)
Example
:FETC?
1023.579E-3
Note
Binary data is returned when the Binary sending format is selected.
Measuring (Awaiting Triggers and Reading Measurements)
Syntax
Query
:READ?
Description
Switches from the Idle State to the Trigger Wait State, then reads the next measured value. With
auto-ranging enabled, the most suitable range is selected before measurement.
See: "Measurement Value Formats" (p. 140)
Error
•
This command causes an execution error if issued during the Continuous Measurement state
(after :INITIATE:CONTINUOUS ON).
• This command causes an execution error if issued during the Trigger Wait State.
Note
•
The next command does not execute until measurement is finished.
• When using an external trigger source (EXT) with auto-sending of measured values (Auto-
Memory function) enabled, returned measured values will be duplicated. Therefore, disable the
Auto-Memory function when triggering externally.
See: "6.4 Auto-Exporting Measured Values (at End of Measurement) (Data Output Function)" (p.
77)
• Binary data is returned when the Binary sending format is selected.
Trigger Source Operation
IMMediate Triggers and reads measured value.
EXTernal Triggers by TRIG
signal (EXT I/O) input, and continuously reads
measured values.
