Commands That Require a Clean Sweep

Many front panel commands disrupt the sweep in progress. For example, changing the channel
or measurement type. When the analyzer does execute a disruptive command in a sequence,
some instrument functions are inhibited until a complete sweep is taken. This applies to the
following functions:
autoscale
n
data + memory
n

Forward Stepping In Edit Mode

In the sequence modify mode, you can step through the selected sequence list, where the
analyzer executes each step.
A title may contain non-printable or special ASCII characters if you download it from an
external controller. A non-printable character is represented on the display as T.

Sequence Size

A sequence may contain up to 2 kbytes of instructions. TypicaIly, this is around 200 sequence
command lines. To estimate a sequence's size (in kbytes), use the following guidelines,
Embedding the Valne of the Loop Counter In a Title
must limit the title to three characters if you wilI use it as a disk file name. The three-character
title and five-digit loop counter number reach the eight-character limit for disk lile names)
This feature is useful in data logging applications.
You can define a sequence to run automatically when you apply power to the analyzer. To
make an autostarting sequence, create a sequence in position six and title it "AUTO". To stop
an autostartmg sequence, press ml. To stop an autostarting sequence from engaging at
power on, you must clear it from memory or rename it.

The GPIO Mode

The instrument's parallel port can be used in two different modes. By pressing m and then
.
The GPIO mode switches the paraIle1 port into a "general purpose input/output" port.
In this mode, the port can be connected to test hxtures, power supplies, and other peripheral
equipment that the analyzer can interact with through test sequencing.
