System interface
-Be sure to use control software applicable to the service requests
when the GP-600B is used with the service requests enabled.
-Give listen-only specification from the controller when the GP-600B
is used in the listen-only mode.
●
Output ripple noises
-When the GP-600B is connected with the regulated DC power
supply units, the DC power supply units may output more ripple
noises than those in individual operation. This is because the
cables lead to bad influences upon noises or the regulated DC power
supply units amplify ripple noises output from the GP-600B.
●
Precautions for connection
-The GP-600B converts digital signals through the GP-IB bus into
analog signals with two D/A converters in two isolated channels and
outputs individual four-channel analog signals. However, do not
use the reference channels B and D in the floating condition. Such
operation does not guarantee the proper performances. Be sure
to connect the negative (-) output of the channel B with the negative
(-) output of the channel A and the negative (-) output of the channel
D with the negative (-) output of the channel C, when the channel B
and D are used individually.
