Flann Microwave Model 625-03
5 ETHERNET COMMAND STRUCTURE
This section details the commands available and the valid operands that may be used with them.
5.1 NOTATION
Upper case bold characters represent the (program code) commands, which must appear exactly as listed.
Program code commands are not case sensitive, i.e. upper and lower case characters are accepted. The
input buffer is 50 bytes maximum.
Characters enclosed in the {} brackets are qualifiers attached to the basic command. A space may be
inserted between it and basic command, e.g. {ON|OFF} shows that either ON or OFF can be attached to
the root mnemonic.
For example, the ‘HOLD_SET’ command has three possible applications:
1. HOLD_SET ON - Switch on the Hold_Set
2. HOLD_SET OFF - Switch off the Hold_Set
3. HOLD_SET? - Query the present state of the Hold_Set
Each program command must be terminated with \n (Hex 0x0a), unless using Telnet
For example: ‘VALUE_SET45.3\n’
For instrument state commands (identified with ‘Query: Valid’), append the question mark character (?)
to the basic command without qualifiers to interrogate the state of the functions. The instrument
responds to the query as described for each command. For an ON/OFF command, the response is a ‘1’ or
a ‘0’ to indicate On or Off. For a settable function, such as VALUE_SET value, using VALUE_SET? returns
the function’s current value.
5.2 COMMAND SET
Note that for the Model 30625-03 only, the standard attenuation is 0 to 50 dB (rather than 0 to 60 dB),
and therefore 50 dB is the maximum setting unless HIGH_ATTEN is on.
VALUE_SET [value]
Sets the attenuation of the microwave instrument, in dB, to value
Query: Valid, returns setting
Value 0 to 60.0 (dB)
STEPS_SET [value]
Sets the attenuation of the microwave instrument, in steps, to value
Query: Valid, returns number of steps from reference
Value 0 to 9799
VANE_STEPS
Returns the vane position in steps without calibration.
Query: Valid, i.e. 60dB = 10099 when the calibration is -300
INCR_SET value
Sets the stored increment to value
Query: Valid, returns stored increment
Value 0 to 10 (dB)
INCREMENT
Increase the microwave instrument setting by the stored increment (dB only)
Query: Invalid
