millivolt generator

[Sajeesh]

hi.........

i am having a DAQ 6024 E and SCB 68.How can i programe in labview  to generate 0 milliVolt to 100  milliVolts.My application needs basic increment of 0.5 millivolts.Is it possible...

You should be able to answer this question yourself by simply looking at the specs. Did you even try searching for them? Why don't you just do a search for 6024E? If you can't find the answer in less than 5 minutes, post  back.

sorryyyyyy......i cant find the answer.... but when i have tried to generate millivolts...i was getting output in steps of 4.88millivolt ...multiples of 4.88 millivolt ...would be (Max Daq output-Min Daq Output)/2 raised to 12....so can i decrease the step size by changing dac reference volage?or by changing the Daq otput Max or Daq output min?The default values of dac reference volatage is 10 volt and that of Maximum is 10 volt and minimum is -10 volt

Did you really search for 6024E? Here's the page. Click on the specifications tab.

when i have gone through specifications of 6024 E....the below mentioned details i got....so can  i customize the card? or is it a hardware limitation?

Max Voltage	10 V
Maximum Voltage Range	-10 V , 10 V
Maximum Voltage Range Accuracy	8.127 mV
Minimum Voltage Range	-10 V , 10 V
Minimum Voltage Range Accuracy	8.127 mV

How about using a 100:1 voltage divider?

Here is a nice one (better than the card 😉 ), however with this card I would use a 8k2 and 100R with a low offset OP for buffering if needed and do the rest in software... (or add a 200R trim, but two R with same tempco are better for stability)
