Controlling the Output Levels
Controlling the Output Levels - Concepts
When the output levels are changed at the M8020A/M8030A/M8040A
data and clock output ports, four parameters are changed:
•V
high
•V
low
•V
amptl
•V
offs
The M8020A/M8030A groups these parameters into "pairs" (V
ampl
/V
offs
,
V
high
/V
low
). If one of these values is modified, its "partner" remains
constant and the values in the other pair are modified accordingly. For
example, if V
ampl
is changed, V
offs
stays constant and V
high
and V
low
are
modified accordingly.
Controlling the Output Levels - Procedures
Changing the Voltages with SCPI
The following commands show how you would set the data output so that
it has an amplitude of 1 V and an offset of 0.5 V:
:SOUR:VOLT:AMPL ‘M1.DataOut1’,1; OFFS ‘M1.DataOut1’,0.5
This sets the output accordingly (V
high
= 1 V, V
low
= 0 V).
Conversely, you could set V
high
and V
low
directly:
:SOUR:VOLT:HIGH ‘M1.DataOut1’,1;
LOW ‘M1.DataOut1’,0
