USB Interface Connector
This interface allows remote control and data transfers between the
841-P-USB and a computer that has a USB communication port.

Analog Output
The analog output is a voltage that can be used to monitor average power
or energy by using external equipment such as an oscilloscope, a chart
recorder, a computer with an analog interface, a voltmeter, etc. This
should be terminated into 1 M
or greater impedance.
The user must enter the maximum value in the
Settings / SET Max
Analog Out Range
menu (see section 2.3.2.9). This value is the value at
which the analog output is equal to 2.05 V. This will provide the best
signal-to-noise ratio. The measured power or energy is then related to the
output voltage and to the selected range according to the following
equation:
