Instrument Control Commands
CMOS(?) i,{j}
CMOS Output
Set (query) the i
th
component of the CMOS output {to j}.
The parameter i selects the CMOS component.
i Value
0
CMOS low voltage
1
CMOS high voltage
Example
CMOS 1, 2.5<CR> Set CMOS high to 2.5 volts.
CMOS?0<CR>
Query CMOS low voltage.
DISP(?){i} Display
Set (query) the current display value {to i}.
The parameter i selects the display type.
i Display
0 Frequency
1 Phase

The query form returns –1 if the current display does not correspond to one of the
standard displays. This might occur, for example, if one of the status displays
were active.
FREQ(?){i} Frequency
Set (query) the frequency {to i}.
PHAS(?){i} Phase
Set (query) the phase {to i}. Note that this command is executed as an
overlapped operation. If necessary, use *OPC or *WAI to determine when the
operation is complete.
PRBS(?){i} Enable
PRBS
Set (query) the PRBS enabled state {to i}. If i is 0, PRBS is disabled. If i is 1,
PRBS is enabled.
QOUT(?) i,{j}
Q / Q
¯ Output
Set (query) the i
th
component of the Q / Q
¯ output {to j}.
The parameter i selects the Q / Q
¯ component.
