Controller
There are three standard configurations that you can use to control the
analyzer.
IBASIC,
in effect, puts a controller inside your analyzer and eliminates the
need for an external controller.
IBASIC
controls the analyzer by sending SCPI
commands to address 800 (OUTPUT 800
;
“Command”), or by using high speed
built-in subprograms. Since
IBASIC
shares CPU time with the analyzer, it
may cause some degradation in measurement throughput if your program
performs intensive computations. However, for most applications, it provides
excellent performance and convenience. Refer to the
HP
Instrument
EASE
User’s Handbook
for more information.
An external controller can be used to control the analyzer. It can be
a personal computer (PC) or an HP BASIC computer. The external
controller sends standard SCPI commands to address 716 (default) (OUTPUT
716 ; “Command”) to control the analyzer. Refer to the Programmer’s
Guide
for more information.
You can use one controller to control several analyzers (see “Expandability
and Large Systems” earlier in this chapter). However, if a large number of
SCPI commands are required per measurement, throughput may be degraded.
Typical limits are 3 to 10 analyzers per computer.
An external computer can control sending SCPI commands via LAN using
a telnet connection. Refer to the
Option
IF’?’
User’s Guide Supplement
for
more information.
You can use one computer to control several analyzers. Performance will
typically be limited by the computer’s speed, which in turn will limit the
number of analyzers per computer.
