OPERATION

REAR PANEL CONNECTORS

 

 

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.

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

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.

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

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.

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. A ls o co n fi g u ra b le t o o u tp u t 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.
