Details
This command reads available data from the remote instrument and returns responses for the
specified number of arguments.
The format string can contain the following specifiers:
%[width]s
Read data until the specified length
%[max width]t
Read data until the specified length or until punctuation is found, whichever comes first
%[max width]n
Read data until a newline or carriage return
%d
Read a number (delimited by punctuation)
A maximum of 10 format specifiers can be used for a maximum of 10 return values.
If formatString is not provided, the command returns a string that contains the data until a new
line is reached. If no data is available, the Series 3700A pauses operation until the requested data is
available or until a timeout error is generated. Use tspnet.timeout to specify the timeout period.
When the Series 3700A reads from a TSP-enabled remote instrument, the Series 3700A removes
Test Script Processor (TSP
®
) prompts and places any errors it receives from the remote instrument
into its own error queue. The Series 3700A prefaces errors from the remote device with "Remote
Error," followed by the error number and error description.
