ANALOGUE OUTPUT COMMANDS
AMODE
Setting the analogue outputs
Disconnect the security lock jumper!
AMODE a bb.bbb cc.ccc d ee.eee ff.fff
a
=
channel 1:
U
=
voltage output
I
=
current output
bb.bbb =
lower limit of channel 1
cc.ccc
=
upper limit of channel 1
d
=
channel 2:
U
=
voltage output
I
=
current output
ee.eee
=
lower limit of channel 2
ff.fff
=
upper limit of channel 2
The bb.bbb, cc.ccc, ee.eee and ff.fff parameters are entered in volts or milli-
amperes.
Sets the analogue outputs on channels 1 and 2. An example: the voltage output
on channel 1 is set to be 0...1 V and channel 2 set to 2...10 V:
>AMODE U 0 1 U 2 10
Ch1 : 0.000 ... 1.000 V
Ch2 : 2.000 ... 10.000 V
The current settings can be checked by giving the command without any pa-
rameters:
>AMODE
Ch1 : 0.000 ... 20.000 mA
Ch2 : 0.000 ... 20.000 mA
ASEL
Selecting the scaling the analogue output quantities
Disconnect the security lock jumper!
ASEL xxx yyy
xxx
=
channel 1's quantity
yyy
=
channel 2's quantity (aw, T)
