Remote control and programming
External analog programming and
monitoring interface
In addition to front panel and remote interface
control, current values can also be programmed
with an analog control signal. The electronic
loads can be externally controlled from zero to
full scale with a 0 to 10 V input signal. A BNC
output is available on the rear for monitoring
the current with a 0 to 10 V output signal.
Voltage-on (Von) latch operation
Control the input turn on state for the DC
electronic load by configuring the Von latch
functions. This can be used to start and stop
discharging of a battery or other power source
once a specified voltage level is reached.
Application software
PC software is provided for front panel
emulation, generating and executing test
sequences, or logging measurement data without
the need to write source code. Additionally, this
application software integrates with NI Data
Dashboard for LabVIEW applications, allowing
users to create a custom dashboard on a tablet
computer or smart phone to remotely monitor
8500B Series DC loads.
n Remote monitoring on iOS, Android or
Windows 8 compatible tablets or smartphones
n Log voltage, current, and power values with
timestamp
n Run transient operation and list mode
programs remotely
n Create an unlimited number of external list
files to be executed from PC memory
Built-in rise and fall time measurement
The 8500B Series can measure the rise or fall time from a specified start and stop voltage level of the
measured input without the need for an oscilloscope. This function can also be used as an internal
timer to count how long the input has been enabled.

The 8500B series supports the SCPI
protocol which is the industry standard for
remote communication. The 8500B series also
maintains backward compatibility for system
integrators still using the legacy 8500 series
proprietary (26 byte) protocol.
