Programming Examples
Example 24: Input Floating P oint or ASCII Trace Data
This example writes trace data to the receiver in either Floating P oint (FORM 3) or ASCII
(FORM 4) formats . The data array is continuously re-written to the display with an oset added
each time . Note the dierence in speed between the two data formats .
Example 25: T able Delay Operations
This example demonstrates how to input, output and apply T able Delay . The Delay T able in also
stored and loaded using the receiver internal disc .
Example 26: F AST (CW ,AD ,D) Data A cquisition
F ast CW setup and operation is demonstrated using an external trigger source . Once the data is
collected, it is converted from FORM 1 to real, imaginary data pairs . See Chapter 8, A utomatic
Measurements , in the HP 8530A Microwave R eceiver User's Guide for more information on the
fast CW mode .
Example 27: F ast IF Multiplexing Operation
This example has been written as a stand-alone program which sets-up a fast IF multiplexing
mode measurement of two parameters (using FASMUXMODE 2; ) and then measures and transfers
the data to the controller . The measurement and transfer will continue until the user exits the
program or until the 100k buer overows . See Chapter 8, A utomatic Measurements , in the
HP 8530A Microwave R eceiver User's Guide for more information on the fast CW mode .
General HP-IB Programming
After the HP-IB REMOTE command is issued, addressing the receiver using an appropriate
OUTPUT statement causes the receiver to enter the Remote mode in which the front panel
hardkeys and softkeys are locked out. The only key that is no locked out is the 4 LOCAL 5 key .
After the initial OUTPUT statement, either ENTER or OUTPUT statements are accepted.
Press the 4 LOCAL 5 key to restore front panel control functions until the next OUTPUT command is
received. Program the Local Lockout command, LLO , to lock out the front panel completely ,
even the 4 LOCAL 5 key . Issue the HP-IB LOCAL command to cancel Local Lockout, then issue a
REN command to return the receiver to remote command.
If the receiver is already addressed as a listener , a GTL 716 (LOCAL 716) sets the receiver
system to the normal manual mode without changing the current instrument state .
All HP-IB Universal and A ddressed Commands and the receiver system response to the
commands are listed below . computer-specic and language considerations are discussed in the
\Example Program Listings" later in this chapter .
