5.4.1 Analogue output commands

5.4.1.1 Setting the analogue outputs

Disconnect the security lock jumper!

AMODE a bb.bbb cc.ccc d ee.eee ff.fff <cr>

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

milliamperes.

Example:

lower limit of channel 1 is 0 V and upper limit 1 V (U 0 1)

lower limit of channel 2 is 2 V and upper limit 10 V (U 2 10)

AMODE U 0 1 U 2 10 <cr>

Ch1 : 0.000 ... 1.000 V

Ch2 : 2.000 ... 10.000 V
