RELATTN Function:
Sets attenuation relative to the reference setting
Syntax:
RELATTN atten
Argument(s): atten
real desired value, in dB
Remarks:
This function sets the attenuation of the currently selected channel to atten, relative to the
reference value set when the REL command was executed.
Return Value:
none
Example(s):
RELATTN 10 increases the attenuation setting 10dB from the reference setting RELATTN -
10 decreases the attenuation setting by 10dB from the reference setting
15.
RELATTN? Function:
Read relative attenuation of the current channel
Syntax:
RELATTN?
Argument(s):
none
Remarks:
This function reads the relative attenuation of the currently selected channel.
Return Value:
relatten real relative attenuation value, in dB
Example(s): RELATTN? returns ’-10.00’
STEPSIZE Function:
Sets attenuation stepsize for the current channel
Syntax:
STEPSIZE atten
Argument(s): atten
real desired stepsize value, in dB
Remarks:
This function sets the attenuation stepsize for the INCR and DECR commands for the
current channel to atten. The default value of the attenuator’s stepsize is the intrinsic
resolution of the attenuator, i.e., a 127dB/1dB step attenuator has a default stepsize of 1dB.
Return Value:
none
Example(s):
STEPSIZE 10 changes the stepsize to 10dB
STEPSIZE? Function:
Read attenuation stepsize
Syntax:
STEPSIZE?
Argument(s):
none
Remarks:
This function reads the attenuation stepsize of the current channel.
Return Value:
atten real attenuation stepsize value, in dB
Example(s):
STEPSIZE? returns ’10.00’
INCR Function:
Increments attenuation
Syntax:
INCR
Argument(s):
none
Remarks:
This function increments the attenuation setting of the current channel by the value of the
attenuator’s programmed stepsize (see STEPSIZE command).
Return Value:
none
Example(s):
INCR
DECR Function:
Decrements attenuation
Syntax:
INCR
Argument(s):
none
Remarks:
This function decrements the attenuation setting of the current channel by the value of the
attenuator’s programmed stepsize (see STEPSIZE command).
Return Value:
none
Example(s):
DECR
