Measurements
This section explains the basic TETRA measurements that are supported in the
STABILOCK, in both asynchronous (Measure) and call mode. Where a measure-
ment applies to call mode only, this is indicated.
Measurements under remote control
Measurements can be controlled either manually, or by AUTORUN programs or
through the GPIB (IEEE-488 bus). Chapter 8 of the STABILOCK 4032 user
manual details the general approach for GPIB control – connecting a PC,
selecting the GPIB address, changing between masks, setting values for the
input variables, reading measurement results. This section describes how to
initiate single-shot TETRA measurements under AUTORUN or GPIB control. The
following sections describe the measurements and the format of result fields.
In remote mode, the STABILOCK can perform single-shot measurements, as
opposed to continuous measurements in manual mode. In order to initiate a new
measurement, the following command is needed:
SPECIalMEAS
On graphical displays, the measurements are stopped after each result has been
returned to the controlling PC until a new SPECIalMEAS command has been
issued. On screens with purely numerical results, measurements run continu-
ously but return results to the controlling PC upon a SPECIalMEAS command.
Once a measurement has been initiated with SPECIalMEAS, results can be
fetched with the RESULTx command, where x and the resulting output format is
detailed below for each measurement separately; see appropriate box entitled
"Test results under remote control".
