Creating NMT Tests
Downloading Programs
Once programs are entered into the Test Set’s IBASIC Controller’s RAM and
saved on mass storage, they can be retrieved and run from the NMT Decoder.
Downloading A Program Into IBASIC Controller RAM
To copy a program from your BASIC computer to the Test Set’s RAM, follow
these steps:
1. Connect an HP-IB cable from your BASIC computer to the Test Set.
2. Load the program into your computer.
3. Set the HP-IB
Mode
field in the I/O CONFIGURE screen to
Talk&Listen
.
4. Enter the following commands on your computer:
OUTPUT Addr;"PROG:DEL"
OUTPUT Addr;"PROG:DEF #0"
LIST #Addr
OUTPUT Addr;" "END
Addr is the HP-IB address of the Test Set.
The END statement indicates that EOI is asserted with the last byte sent. (Refer to
IEEE 488.2 standards for more information.)
NOTE: Although your NMT program is now in the Test Set’s IBASIC program RAM, it cannot be
run from the TESTS (IBASIC Controller) screen, since IBASIC does not recognize the NMT
commands. You must copy the program to mass storage before it can be run in the decoder.
Copying Programs to Mass Storage
Programs copied to RAM disk, external disk, or memory cards require specific
initialization and configuration procedures for proper storage and retrieval. Refer
to the Programmer’s Guide.
