8.1.3.5 Analog Output
[AP] Analog Span
NAME: ANALOG SPAN
SYNTAX:
[APXXXXX] or [AP]
PARAMETERS:
XXXXXXX is the wanted span (positive integer). The parameter corresponds to
the cavity length change per 5000 mV (fixed value). As example, [AP50]
corresponds to 50nm/5000 mV = 0.01nm/mV.
If none: Return the current value of the span.
For conversion purpose, we define also 0.01 nm/mV factor as AP
f
.
REMARKS:
This command is used to set the SPAN of the analog output. Used without
parameter, this command returns the actal span value stored in the conditioner.
RETURN VALUE:
APXXXXX\n\r ;Echo
“***** Quitting the expert mode *****”
(or)
AP\n\r ;Echo
XXXXX\n\r XXXXX is the current value of the span.
ERROR NUMBER:
10
[AZ]: Analog Zero
NAME: ANALOG ZERO
SYNTAX:
[AZXXXXX.XX], [AZ]
PARAMETERS:
XXXXX.XX is a positive or negative number that sets the ZERO (Analog Offset)
on the analog output. XXXXX.XX is the value in physical units of the 0Volts
position. Values must be comprised between -20 000 à 20 000.
If none: returns the current ZERO (Analog Offset) value from the analog output.
REMARKS:
It is not recommended to use this command with a parameter other than 0.
RETURN VALUE:
AZXXXXX.XX\n\r
(or)
AZ
XXXXX.XX\n\r (XXXXX.XX is the current ZERO value from the active channel
analog output)
ERROR NUMBER:
10
