Making Measurements
Using Test Sequencing
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
• data → memory
Forward Stepping in Edit Mode
In the sequence modify mode, you can step through the selected sequence list, where the
analyzer executes each step using the .
Titles
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 π.
Sequence Size
A sequence may contain up to 2 kbytes of instructions. Typically, this is around 200
sequence command lines. To estimate a sequence's size (in kbytes), use the following
guidelines.
Embedding the Value of the Loop Counter in a Title
You can append a sequentially increasing or dec r easi ng numeric value to the title of stored
data by placing a command after
the title string. (You must limit the title to three characters if you will use it as a disk file
name. The three-character title and five-digit loop counter number reach the
eight-character limit for disk file names.) This feature is useful in data logging
applications.
Autostarting Sequences
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 (SEQ6) and title it
“AUTO”. To stop an autos tarti ng s equence, press . To stop an autostarting sequence
from engaging at power on, you must clear it from memory or rename it.
