E2730A VXI RF TUNER 

 

 

 

 

 

OPERATION 

3-1 

SECTION 3 

OPERATION 

 

3.1  INTRODUCTION 

 
 

The E2730A VXI RF Tuner is controlled  using either word serial 
commands or binary commands via  the VXI Interface.  In addition, the 
RS-232 port (AUX, located on the front panel) also accepts the same 
mnemonics that are used with the word serial VXI commands.  The 
following paragraphs provide the details required for the system integrator 
to access, control, and monitor the tuner's operation.  The following 
discussions assume that the system integrator is familiar with the rules and 
guidelines contained in the VXIbus Specification and RS-232 interface 
specifications.  A copy of the VXIbus Specification can be requested by 
writing to: 

 
 

VXIbus Consortium, Inc. 

 

P.O. Box 1736 

 

Vancouver, WA  98668 U.S.A. 

 

3.2  INDICATORS 

 
 

All tuner indicators are located on the front panel.  Two LEDs are 
provided for monitoring the operating status of the unit.  The following 
paragraphs further explain the function of each LED.  The E2730A has no 
front panel controls. 

 

3.2.1  RUN INDICATOR, GREEN LED 

 
 

This green LED illuminates approximately one second after power is 
applied to the tuner, indicating that the tuner’s microcontroller is active 
and running properly. 

 
3.2.2  ERR INDICATOR, RED LED 

 
 

This red LED illuminates when internal diagnostic circuitry detects any of 
the following tuner errors: 

 

 

•

 

Any Unlocked LO 

 

•

 

EEPROM Defaulted (illuminate for three seconds only) 

 
 

Note that the ERR indicator does not indicate the receipt of invalid remote 
messages.
