Name

SRSfunc_gen - Stanford Research DS335 function generator I/O service

Synopsis

SRSfunc_gen <argument list>

Description

Serial I/O service for a Stanford Research DS335 function generator.

The program expects to find several RefNames under the label specified on the command line.

Arguments

--dbman_host <hn>

The host where dbman is running.

If this argument is not supplied the default is "localhost". If the DBMAN_HOST environment variable is present is overrides the default. This argument in turn overrides previous settings.

--local <path>

The path name of the device to open for local mode.

Note that the local or remote option must be specified.

--remote <host>,<sock>

The remote host and socket to connect to.

Note that the remote or local option must be specified.

--label <label>

A label from the database.
--help

Prints the help message and exits.

Argument Usage

Argument processing is done using Unix long argument syntax. For remote mode, the port number is extracted from /etc/services. Supposedly this can also be a numeric value.

Function Generator Control Database RefNames

The RefNames in this group relate directly to parameters in the function generator.

Please consult the function genertor manual for more information.

SRSrst


This is a command to the program to reissue the initialization and resync the function generator with the database.

SRSam


Amplitude Control

SRSfc


Frequency Control

SRSwv


Waveform Selection.

Function Generator Initialization

When the program is started or a reset is issued the function generator is initialized in the following way:

set ttl output level
set DC offset to 0v
turn sync output on
set termination to hiZ
turn sweep off

Notes

Not all of the function generator parameters are supported. This may be expanded in the future.

The function generator needs to have RS232 communication enabled and the baud rate set to match the com port settings.

Examples


#
# local port connection
stty 9600 < /dev/ttyS0
SRSfunc_gen --dbman_host csdev1 --local /dev/com2 --label "SCX TA-1"
#
# communication using a terminal server
#
SRSfunc_gen --dbman_host csdev1 --remote csdev11,ETSraw1 --label "SCX 02-1"

Note that the label will need to be quoted for the shell to treat it as a single argument.

Note also that the example lines are very long and have probably been wrapped by the software which produced by formatted manual page.
