Rear Panel Connectors Connections
4-4 PN: 10585-00001 Rev. P ML2437A/38A OM/PM
M Input 2, Analog Multi-purpose BNC connector used for Volts per GHz connection.
Supports 0 to +20 V nominal input voltage with software
selectable scaling. V/GHz is used for automatic CAL FACTOR
correction by applying an external voltage, scaled to frequency.
The correct calibration factor for this frequency is automatically
interpolated and applied when in V/GHz calibration factor mode.
Different scaling may be applied to sensor A or B allowing for
measurement of frequency translation devices. Available
simultaneously with channel A and/or B data, the data rate is as
set on the channel. The default data rate is 20 ms in DEFAULT
measurement mode (with the default settling time of 0.1 %), and
programmable in PROFILE operation mode and CUSTOM
measurement mode.
N DC Power Supply
Input
Used for 12-24 VDC input in the absence of AC line power. The
optional battery can be fast-charged when the DC input voltage is
greater than or equal to 21 V and all other functions are off.
Fast-charge must be selected from the System menu. The
external DC Power Supply input line is protected by an internal
fuse.
