USB Model Pulse Sensor
The USB model Pulse Sensors receive power and communicate over the USB
port.
Monitor/Control
Bird’s Virtual Power Meter (VPM3) software may be used to provide control and
monitoring of the sensor. A USB cable is used to connect the Power Sensor to a
PC running the VPM3 software.
The USB sensor may also be controlled using Standard Commands for
Programmable Instrumentation (SCPI) over USB. Refer to the 7027 Pulse Sensor
Programming manual for details regarding SCPI commands.
Measurement
The 7027 is a multi-level pulse power sensor. It measures the average power of
up to four levels within a pulse period. Each state is defined with begin and end
times within the VPM3 user interface (State Average Measurement). The begin
and end times are referenced to the internal reference signal or may be
referenced to an external sync pulse. See
for a complete explanation.
