DO
This command requests readings.
Usage
DO 'AAAAAA'
AAAAAA
Details
After making measurements, use this command string to request the readings. After the 4200A-SCS
is addressed to talk, the readings are sent to the computer.
To access the timestamp data that was acquired along with voltage or current measurements or
both, use the command:
DO 'CHnT'
where: n = Absolute channel number. Unlike V-and I-name strings, this label cannot be changed
through the CH or VS commands.
Output data is sent to the computer in the format:
X±N.NNNN E±NN,
Where X is the status of the data (where X = N for a normal reading), followed by the reading
mantissa and exponent. You can set the delimiter to CR/LF or Comma, and enable or disable EOI.
Example
DO 'Volt'
This command string requests the reading string for a SMU channel that is named Volt.
