Chapter 3, Operating Overview
Increasing Measurement Throughput
Minimizing bus configuration time
Every time a BASIC or IBASIC OUTPUT or ENTER statement is executed, the bus (HP-
IB) has to be configured for data transfer. Using compound HP-IB statements minimizes
bus configuration time by combining several operations into one HP-IB OUTPUT or
ENTER statement.
To combine multiple HP-IB commands into one OUTPUT statement, use the ;
(semicolon) separator and/or the ;: (semicolon colon) separator.
NOTE: It may be helpful to add the common command *OPC following a compound HP-IB
command. The *OPC command is used to synchronize the control program with the Test Sets’
operating state. For a description of the *OPC command, refer to the HP-IB Common
Commands chapter of the HP 8924C Condensed Programming Reference Guide.

Using the semicolon in compound OUTPUT statements
The following example sets the Traffic Data Mode to Service Option 2 and the Data
Rate to Full. The semicolon separator causes the HP-IB command parsor to back
up one level in the command hierarchy.
The following example...
• 10 OUTPUT 714;"CDMA:CALL:TRAFFIC:DATA:MODE ’Svc Opt 2’", and
• 20 OUTPUT 714;"CDMA:CALL:TRAFFIC:DATA:RATE ’Full’"
could be replaced with:
OUTPUT 714;"CDMA:CALL:TRAFFIC:DATA:MODE ’Svc Opt 2’;RATE ’Full’"
Using the semicolon-colon in compound OUTPUT statements
The following example sets the Sector A Power level to -70 dBm, then attempts
to make a call. The semicolon-colon separator causes the HP-IB command
parsor to back up to the top level in the command hierarchy.
OUTPUT 714;"CDMA:CELL:ASECTOR:BWPOWER -70 DBM;:CDMA:CALL:MAKE"
