DISPLAY and OUTPUT COMMANDS
DDEF (?) { j, k}
FPOP (?) {j}
OEXP (?) i {, x, j}
AOFF i
The DDEF command selects the CH1 display. The DDEF j, k command
sets the CH1 display to parameter j with ratio k as listed below.
CH1 (i=1)
j display
0 X
1 R
2 X Noise
3 Aux In 1
4 Aux In 2
k ratio
0 none
1 Aux In 1
2 Aux In 2
The DDEF? command queries the display and ratio of the display. The
returned string contains both j and k separated by a comma. For
example, if the DDEF? command returns "1,0" then the CH1 display is R
with no ratio.
The FPOP command sets or queries the CH1 front panel output source.
The FPOP j command sets the output to quantity j where j is listed
below.
CH1 (i=1)
j output quantity
0 CH 1 Display
1 X
The OEXP command sets or queries the output offsets and expands.
The parameter i selects X (i=1), Y (i=2) or R (i=3) and is required. The
parameter x is the offset in percent (-105.00 ≤ x ≤ 105.00). The
parameter j selects no expand (j=0), expand by 10 (j=1) or 100 (j=2). The
OEXP i, x, j command will set the offset and expand for quantity i. This
command requires BOTH x and j. The OEXP? i command queries the
offset and expand of quantity i. The returned string contains both the
offset and expand separated by a comma. For example, if the OEXP? 2
command returns "50.00,1" then the Y offset is 50.00 % and the Y
expand is 10.
Setting an offset to zero turns the offset off. Querying an offset which is
off will return 0% for the offset value.
The Y offset and expand may only be set using the OEXP command.
The Yoffset and expand only affect the rear panel Y output. Overloads
on Y are not reported by the SR810.
The AOFF i command automatically offsets X (i=1), Y (i=2) or R (i=3) to
zero. The parameter i is required. This command is equivalent to
pressing the [Auto Offset] keys.
