ML2437A/38A OM/PM PN: 10585-00001 Rev. P 4-3
C GPIB/ IEEE488
Connector
Standard General Purpose Interface Bus connector used to
connect through GPIB to other test equipment and a host
computer. The ML243xA is compatible with IEEE-488.1
requirements.
D ID Number Label The ML243xA ID number is affixed to the rear panel here. Please
use the complete ID number when ordering parts or
corresponding with the Anritsu Customer Service department.
E AC Main Power
Input
85-264 VAC, 47-440 Hz, 40 VA maximum. The power meter
automatically configures itself for the voltage applied. Connecting
AC power here will turn the instrument on. Subsequently, the
instrument can be switched between the ON state and the
STANDBY state using the front panel ON/OFF button. The
optional battery can be fast charged when AC input voltage is
applied through this connector and all other power meter functions
are off.
F Chassis Ground Used as a convenient earth ground reference when DC line power
is applied. Used as an optional safety ground when operating
from battery power.
GSensor
Connectors
Alternate Sensor input connectors for Channels A and B. If the
rear panel optional connectors are installed, the front panel
connectors are not installed.
HSensor
Connectors
Alternate Sensor input connectors for Channels A and B. If the
rear panel optional connectors are installed, the front panel
connectors are not installed.
I Calibrator
Connector
Alternate Calibrator output connector. If this rear panel connector
option is installed, the front panel connector is not installed. Refer
to Chapter 5, Procedures, for information on using the Reference
Calibrator output.
J Output 1 Multi-purpose BNC connector is user-configurable for Modulation
Output (TTL), Analog Output 1 (volts/units), or Limits Pass/fail
(TTL). Supports pass/fail testing for channels 1 and 2. Also
configurable to output a real-time measurement signal from
sensor input A, suitable for leveling purposes.
K Output 2 Multi purpose BNC connector is user configurable for Analog
Output 2 (volts/units), Blanking Zero (TTL), or Limits Pass/Fail
(TTL). Supports pass/fail testing for channels 1 and 2. Also
configurable to output a real-time measurement signal from
sensor input B, suitable for levelling purposes.
L Input 1, Digital Multi purpose BNC connector is user configurable for Blanking
Input (used to ARM measurements in triggering modes) or TTL
Trigger Input.
