3.1.7. GET Command

The GET command allows to read the current/voltage/power value at the output of the power unit..

Command Format:

R/W	Command	Response	Description
R	GET:I:?	#GET:I:<out_I>	Return the output current read - averaged value
R	GET:V:?	#GET:V:<out_V>	Return the output voltage read - averaged value
R	GET:P:?	#GET:P:<out_P>	Return the output power read - averaged value
R	GET:I:SAMPLE:?	#GET:I:SAMPLE:<inst_out_I>	Return the output current read - instantaneous value
R	GET:V:SAMPLE:?	#GET:V:SAMPLE:<inst_out_V>	Return the output voltage read - instantaneous value
R	GET:P:SAMPLE:?	#GET:P:SAMPLE:<inst_out_P>	Return the output power read - instantaneous value
R	GET:AUX:?	#GET:AUX:<aux_voltage>	Return the voltage read on the auxiliary input

Parameter(s):

Name	Type	Unit	Description
<out_I>	float string	[A]	Output Current read (averaged)
<out_V>	float string	[V]	Output Voltage read (averaged)
<out_P>	float string	[W]	Output Power read (averaged)
<inst_out_I>	float string	[A]	Output Current read (instantaneous)
<inst_out_V>	float string	[V]	Output Voltage read (instantaneous)
<inst_out_P>	float string	[W]	Output Power read (instantaneous)
<aux_voltage>	float string	[V]	Auxiliary Voltage read

Tip

To improve the signal-to-noise ratio, the GET:I:? / GET:V:? / GET:P:? commands return values that are calculated using a 2-stage moving average filter. * The first moving-average stage has a length of 8 samples, the second filter has the length of 1024 samples. * The first filter is running at a “native” frequency of is 100kHz (see UPFREQ Command); the second filter is receiving decimated data (by a factor 4) from the first filter, the frequency is therefore for example: 100/4 = 25 KHz.

Tip

The AUX Input signal is optional, read the Optional Boards section to verify which extension boards mount it. The AUX measuring range is bipolar: AUX [-10V, +10V].

Example(s):

GET:I:?
#GET:I:5.4871231

GET:V:SAMPLE:?
#GET:V:SAMPLE:3.8769825
