OPERATION REAR PANEL CONNECTORS
Figure 3-2. ML2430A Series Rear Panel
GPIB/ IEEE488 Connector
Standard General Purpose Inter-
face Bus connector used to con-
nect through GPIB to other test
equipment and a host computer.
The ML2430A Series is compatible
with IEEE-488.1 requirements.
Refer to Chapter 6, GPIB Program-
ming for information on using
GPIB.
Parallel Printer Port
Provides an interface to a stan-
dard parallel printer. Compatible
printers include the Canon BJC80,
HP 340 Deskjet, and most other
300 and 500 Series HP Deskjet
printers.
ID Number Label
The ML2430A Series ID
number is affixed to the rear
panel here. Please use the
complete ID number when
ordering parts or corre-
sponding with the Anritsu
Customer Service depart-
ment.
AC Main Power Input
85-264 VAC, 47-440 Hz, 40 VA maximum. The Power Meter automati-
cally 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 func-
tions are off.
RS232 Serial Connector
Serial control and data output commands are
entered using the same format as the GPIB in-
terface. Refer to Section 5-9 for more informa-
tion on using Serial Remote Operation. Allows
communication with an Anritsu 68/69000-series
synthesizer in Source Sweep mode. Also allows
service access for software upgrades, etc. The
hardware handshake lines RTS and CTS are
used to control the flow of data.
Sensor Connectors
Alternate Sensor input connec-
tors for Channels A and B. If the
rear panel optional connectors
are installed, the front panel
connectors are not installed.
Calibrator Connector
Alternate Calibrator output con-
nector. If this rear panel connector
option is installed, the front panel
connector is not installed. Refer to
Chapter 5, Procedures, for infor-
mation on using the Reference
Calibrator output.
Chassis Ground
Used as a convenient earth ground
reference when DC line power is
applied and an optional safety
ground when operating from battery
power.
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 21V and all other functions are
off. Fast charge must be selected from the
Sys-
tem menu. The external DC Power Supply input
line is protected by an internal fuse
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.
Output 2
Multi purpose BNC connec-
tor is user configurable for
Analog Output 2 (volts/units),
Blanking Zero (TTL), or Lim-
its Pass/Fail (TTL). Supports
pass/fail testing for channels
1 and 2. Also configurable to
output a real-time measure-
ment signal from sensor in-
put B, suitable for leveling
purposes.
Input 1, Digital
Multi purpose BNC con-
nector is user configur-
able for Blanking Input
(used to ARM measure-
m e n t s i n t r i g g e r i n g
modes) or TTL Trigger
Input.
Input 2, Analog
Multi-purpose BNC connector used for Volts per GHz connection. Supports 0 to
+20V nominal input voltage with software selectable scaling. V/GHz is used for
automatic CAL FACTOR correction by applying an external voltage, scaled to fre-
quency. The correct calibration factor for this frequency is automatically interpo-
lated 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 de-
vices. 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.
