Remote Interface Operations
DL-1060 Series supports three remote interfaces: the built-in USB, GPIB (G type only),
and RS232 (R type only). With GPIB, you will need a GPIB interface card. This chapter
lists the SCPI (Standard Commands for Programmable Instrument) commands
available to control the multimeter. For the first time to use SCPI, users would better
to refer to Appendix B. for SCPI reference.
4.1 Pass/Fail Output From USB Connector
The USB connector on the rear panel of DL-1060 is a type-B connector. When the USB
interface is
disabled
, the internal pass and fail TTL output signals (limit testing) will
be transmitted to the USB connector.
The pass and fail signals are low true and indicate the Math Pass/Fail Limit Test result
for the
next
reading to be output to the GPIB interface. The signals are active low for
approximately 2ms (
±
100
μ
sec) for each reading taken.
Figure 4-1
shows the USB
connector (type-B).
