FETCh3? (@<channel>)
Waits for module digitizing to complete on the specified channel and transfers all available readings stored in read-
ing memory to the instrument's output buffer. The readings remain in reading memory will not be erased when read
with this command.
The data of incomplete records can't be retrieved.
This SCPI is supported on the DAQM909A Digitizer module only.
Parameter Typical return
(none) (none)
Use the FETCh3? command with ACQuire3 and INITiate3. The ACQuire3 command configures the channels for DC voltage module digitizing
and the INITiate3 command initiates the digitizing process. The FETCh3? command then transfers the readings from reading memory to the
instrument's output buffer.

FETCh3:DATA? [<record #>,[<first_pt>, [<last_pt>]]] (@<channel>)
Returns the specified range of readings on the specified record for a channel.
The data of incomplete records can't be retrieved.
This SCPI is supported on the DAQM909A Digitizer module only.
Parameter Typical return
<record #> = An integer indicating the specified record for a channel.
Default: 1
<first_pt> = An integer indicating the first data point of the range of readings to return
Default: 1
<last_pt> = An integer indicating the last data point of the range of readings to return
Default: Specified Sample Count value
<channel> = Channel number
(none)
Returning a range of readings from data number 2 to 5 in the first record of Digitizer channel 201.
FETCh3:DATA? 1,2,5 (@201)
Typical response: +1.74889548E-02, -2.04363291E-02, +1.74882342E-02, -1.70983737E-02
