13.4.3 Command types
There are three types of commands:
- put commands do not set the hardware, they only transfer data.
- set commands set the hardware.
- meas commands perform a measurement and return the result.
Relationship between ’put’ and ’set’ commands:
Data transferred by means of a put command remain valid until they are overwritten. Data are not
defined prior to their first use.
Example: setting sequence for measuring the output level
put:s1:burst cw
put:s1:freqoff 67014
put:s1:mod off
put:s1:freq 925.2e6
put:s1:lev -50
set:s1
--- measure level ---
put:s1:freq 945.0e6
set:s1
--- measure level ---
put_s1:freq 959.8e6
set:s1
--- measure level ---
put:s1:freq 945.0e6
put:s1:lev -75
set:s1
--- measure level ---
etc
Example: setting sequence for measurement of input power
put:rx:freq 900e6
put:rx:lev 10
; expected power
set:rx ; sets the local TX synthesizer and the input path
meas:pow ; power measurement
etc
Example: setting sequence for diagnosis voltages
put:diag qpll
set:diag
meas:diag
; measurement of control voltage of reference frequency PLL
put:s1:freq 950e6
set:s1
; sets TX synthesizer to 950 MHz
put:diag txpll
set:diag
meas:diag
; measurement of control voltage of TX synthesizer PLL
