POWER [MODPWR] – If this is set, and the power cycles on the
meter, then the number specified in the “phone number” field will be
dialed. When a connection is established, an SRQ will be sent to
the host PC. Remote communications can then continue as normal.

Configures the input and output rear panel BNC connectors.
PORT
Output 1 or 2: Select the output port to configure (see MODE
below).
Input 1: Select what type of Blanking input you are providing (see
TTL LEVEL below) on Input 1.
Input 2: Selects input 2 for V/GHz or External volts input. You can-
not configure the V/GHz or External volts input port here. To config-
ure V/GHz set Sensor|CalFactor|Source to V/GHz. To use the
External Volts Input set Channel|Setup|Input to EXT V.
MODE (output ports only)
OFF (output set to ground) port 1 or 2
Analog OUT (analog scaled output) port 1 or 2 provides an output
voltage proportional to the measurement.
RF Blanking (output 2 only) provides a logic level output during the
ZERO process. This can be used to switch off RF from external
sources.
PASS/FAIL port 1 or 2 logic level output
Signal channel A or B (port 1 or port 2) provides a real time output
from the signal channel. Being real time, it shows modulation, etc.,
and is taken after the signal has been through range amplifiers. It is
not directly proportional to the measurement.
Leveling A or B (range 1 or 2) (port 1 or 2). This is similar to the sig
-
nal channel A or B outputs, except it connects to range 1 or 2 only
of the signal channel. See below for more information on leveling.
