5-112 Data Transfer Commands
SR785 Dynamic Signal Analyzer
TPUT ? i
The TPUT command downloads Trace buffer data to the SR785. This command
is valid only via the GPIB interface. The parameter i selects a Trace (1-5). Trace
i does not need to already contain data.
The download data must be data which was originally uploaded by TGET in its
entirety. The TGET and TPUT commands allow a host computer to save and
reload a Trace buffer without using disks.
The download sequence is as follows:
Host
Send TPUT ? i. Do NOT wait for IFC to be set in the Serial Poll status.
SR785
Returns 1 (4-byte binary long int) when OK to begin binary transfer to the
SR785.
Host
On receipt of 1 (4-byte binary long int), executes a binary transfer to the SR785
of n bytes (as uploaded using TGET). Asserts EOI with the final byte of the
transfer.
SR785
Receives n bytes and the EOI. If an error is detected during transfer, the Trace
buffer reverts to the empty state and a command execution error occurs.
Serial Poll until IFC (bit 7) is set in the Serial Poll status before sending another
command.
AGET ? i
The AGET command uploads the Arbitrary Waveform buffer to the host
computer. This command is valid only via the GPIB interface. The parameter i
selects upload the whole buffer (0) or just the playback portion (1).
The uploaded data should be saved in its entirety by the host computer. The
saved data can be downloaded back to the SR785 at a later time using APUT.
The AGET and APUT commands allow a host computer to save and reload the
Arbitrary buffer without using disks.
The upload sequence is as follows:
Host
Send AGET ? i. Do NOT wait for IFC to be set in the Serial Poll status.
SR785
Returns n (4-byte binary long int) which is the number of bytes needed to
transfer the Arbitrary buffer.
