"D"  DC offset in microvolts

Format

ATdDnpvvvvvvv

where

d = device # (0-9)

n = channel number (1-8) or "?"

p = polarity of offset, positive (+) or negative (-)

vvvvvvv = input referred offset in microvolts (7 digits)

Examples

AT1D2+1234500

Set device 1, channel #2, to +1.234500 volts

AT1D2+1 234 500

Set device 1, channel #2, to +1.234500 volts

AT2D7-0012345

Set device 2, channel #7, to -0.012345 volts

AT2D7-12345

Set device 2, channel #7, to -0.012345 volts

Notes

Because the DC offset is added after the pre-filter amplifier, the input-referred range and resolution

depend on the pre-filter gain.

Pre-filter Input-referred Input-referred

Gain Range Resolution

x1 ±3,000,000 µV 100 µV

x10 ±300,000 µV 10 µV

x100 ±30,000 µV 1 µV

A value outside the above limits will result in an error response of the form "Dn=!". For example:

D2=!

error setting DC offset on channel 2

> end of response

If the "p" polarity indicator is omitted, the default polarity is positive.

The data field can have 1-7 characters, and uses leading zero suppression (e.g., 0000100 is the same

as 100).
