DISPLAY and OUTPUT COMMANDS
DDEF (?) i {, j, k} The DDEF command selects the CH1 and CH2 displays. The parameter
i selects CH1 (i=1) or CH2 (i=2) and is required. The DDEF i, j, k com-
mand sets display i to parameter j with ratio k as listed below.
CH1 (i=1) CH2 (i=2)
j display j display
0 X 0 Y
1 R 1 θ
2 X Noise 2 Y Noise
3 Aux In 1 3 Aux In 3
4 Aux In 2 4 Aux In 4
k ratio k ratio
0 none 0 none
1 Aux In 1 1 Aux In 3
2 Aux In 2 2 Aux In 4
The DDEF? i command queries the display and ratio of display i. The
returned string contains both j and k separated by a comma. For exam-
ple, if the DDEF? 1 command returns "1,0" then the CH1 display is R
with no ratio.
FPOP (?) i {, j} The FPOP command sets or queries the front panel (CH1 and CH2)
output sources. The parameter i selects CH1 (i=1) or CH2 (i=2) and is
required. The FPOP i, j command sets output i to quantity j where j is
listed below.
CH1 (i=1) CH2 (i=2)
j output quantity j output quantity
0 CH 1 Display 0 CH 2 Display
1 X 1 Y
OEXP (?) i {, x, j} 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 parame-
ter 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 com-
mand 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.
AOFF i 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 press-
ing the [Auto Offset] keys.
