Measurement Rate, Advanced Trigger Mechanisms

Additional Considerations 5

Introduction

Chapter 5 discusses some topics that will help you use the instrument more effectively. These considerations assume that you are familiar with the basic operation of the instrument and have some basic understanding of electronics.

Measurement Rate

The two measurement rates provide a choice of maximum accuracy and noise rejection (slow rate) or maximum throughput (fast rate). The selected rate applies to all channels on the instrument. Therefore, your rate selection will be based on overall consideration of the speed and accuracy you need.

Exact measurement rates vary somewhat by type of measurement. Refer to Appendix A, Specifications for complete measurement rate information.

Advanced Trigger Mechanisms

Normally, the built-in scan interval timer controls when scan measurements are taken. However, two additional mechanisms are available for activating scans:

1.An external trigger signal, connected at the rear panel "TR" input.

2.An alarm condition on the Monitor channel.

Note

These two additional trigger mechanisms are mutually exclusive.

The External Trigger input and Monitor-Alarm trigger can be enabled from the front panel or through computer interface commands

Front Panel Trigger Control

To access the trigger controls from the front panel, select TRIGS (K M). Then press

Gor Gto cycle through the choices for trigger types:

OFF	Both External and Monitor-Alarm triggers are disabled.
On	The External Trigger input is enabled.
ALAr	The Monitor-Alarm trigger is enabled.

Press EEonce you’ve selected the desired trigger type. Note that internal scan interval triggering is not affected by this selection and remains available.

Computer Interface Trigger Control

Select a scan trigger type over the computer interface by sending the command:

TRIGGER<type>

where <type> is:

0Both External and Monitor-Alarm triggers are disabled.

1The External Trigger input is enabled.

2The Monitor-Alarm trigger is enabled.

If one of these types is not specified, an Execution Error is generated.
