Section 3: Instrument description
Reset a slot from the web interface
You can reset all the relays in the displayed slot by clicking Reset Slot.
When you reset the relays in a slot:
•
Any closed channels and analog backplane relays open
•
The poles of all channels reset to 2-pole operation and paired channels are changed to match
•
Labels return to default of slot, channel or slot, row, column
•
Analog backplane relays specified by the channel.setbackplane() function are cleared
•
Delays are set to zero
•
If the channel is forbidden to close, it is cleared from being forbidden to close
•
The DMM configurations of all channels are set to nofunction
•
If any of the slot's channels are in channel patterns, the patterns are deleted
The rest of the instrument settings are unaffected.

Scan Builder page

The Scan Builder page allows you to set up and run scans and triggers.
A scan is a series of steps that opens and closes switches sequentially for a selected group of
channels. During each step, actions occur, such as waiting for a trigger, taking a measurement on an
external instrument, and completing a step count. Scans automate actions that you want to perform
consistently and repeatedly on a set of channels.
Triggers are events that prompt the instrument to move from one step to another in a scan. Triggers
can come from a variety of sources, such as a key press, digital input, or expiration of a timer. The
sequence of actions and events that occur during the scan is called the trigger model, described in
Trigger model
Scanning and triggering allow you to synchronize actions across channels. You can set up a scan
using the trigger model to precisely time and synchronize the Series 3700A between channels and
multiple instruments. You can also use triggers without the triggering model to set up a scan to meet
the needs of a specific application that does not fit the triggering model.
If you use Scan Builder to create a scan, use the options in the Scan Builder page to run the scan.
Using the TSB Embedded page may not give you the expected results.
If you create a reading buffer through the Scan Builder page, the name of the buffer must be different
than the name of any scripts in the system.
Create a scan list
Before you can run a scan, you must create a scan list. A scan list is a set of steps that runs in order
during a scan. Each step contains a channel, channels, or channel patterns that you want to measure
in that step. Each step is acted on separately during the scan.
You can mix channel patterns and individual channels in a scan list. Note that the steps are executed
in the order in which they are added to the scan.
