DM 5010 Data Processing
Functions built into the DM 5010 allow you to ob­
tain answers that are already processed or corrected
in a number of ways. For instance, ohms readings can
be offset by NULL to take into account lead resis­
tance. Any reading can be scaled according to the
formula (x-b)/a; this converts a voltage reading across
a resistor to current if b is set to zero and a to the
resistor ’ s ohms value. Voltage readings can be re­
turned in dB or dBr (dB compared to a reference).
Just insert the processing command selected from the
command table in this guide into set-up messages
sent to the DM 5010. An example using the averaging
function is shown in the sample measurement
program.
DM 5010 Response to interface Messages
The following program sequences show various in­
terface messages transmitted to the DM 5010.
The DM 5010 responds to DCL (and SDC if listen
addressed) by clearing its Input and Output Buffers
and any unexecuted setting commands in its Pending
Settings Buffer, along with any errors or events wait­
ing to be reported (except power-on).
GET triggers a reading in device trigger mode if the
instrument receives the message while listen ad­
dressed. It is used with the MODE TRIG and DT TRIG
commands.
LLO locks out the operator from restoring local
(front-panel) control when the instrument is under re­
mote control.
GTL restores local control if the instrument re­
ceives the message while listen addressed.
See the DM 5010 Operators Manual for a full dis­
cussion of how the instrument responds to interface
messages.
