Chapter 6, Problem Solving

If you can’t get the data-collection function to work

❒ Check that you have DATA C entered in the TESTS (External Devices) (or

Edit Config) menu.

1. Press TESTS.

2. Select the External Devices screen, from the SET UP TEST SET list (or

Edit Config from the Test Function field).

3. Position the cursor to the Calling Name field, push the knob and enter:

DATA C.

❒ Check the Model field, it should be kept empty since it is not used.

❒ Check the Addr (address) field to make sure the correct address is entered for where

the data is to be stored.

1. If data is to be stored on an SRAM memory card, enter “1” into the Addr field.

2. If data is to be stored on an external computer through the test set’s RS-232 serial port

(if available), enter “9” into the Addr field.

3. If data is to be stored on an external disk drive over HP-IB, enter an address of “700”

or greater into the Addr field.

❒ Check the Options field to make sure it is correctly set up:

1. For an external disk drive (LIF format) or an SRAM memory card:

a. Enter ASCII for saving data as an ASCII file.

b. Enter BDAT for saving data as a Binary-Data file.

c. As an option, you may enter REC=xxx, where “xxx” is the number of records

for each file. (The software defaults to 80 records. However, if too small a

record size is used, you’ll get an “End of file error” when the test is

run.)

2. For a DOS disk drive, you may keep the Options field empty, or you may enter

any of the following key words:

a. Enter ASCII for saving data as an ASCII file.

b. Enter BDAT for saving data as a Binary-Data file.

c. Enter REC=xxx for the file’s record size, where “xxx” is the number of records

for each file. (The software defaults to 80 records. However, DOS systems

automatically change record size if it’s too small.)

d. Enter a (dot extension) of 3 characters or less for the file name. For

example, all model ABCD radio’s tested may be organized to have a “.ABC”

file extension.
