Simple scanning
NOTE
See Section 7 for details on scanning.
With at least one multiplexer switching module (i.e., Model 7700) installed in the main-
frame, the instrument can scan channels that are valid for the selected function.
For front panel operation, Figure 1-7 shows the three basic steps to configure and run a
simple scan. The differences between the STEP function and the SCAN function involve
the reading count and the timer.
Reading count (RDG CT)
— For both STEP and SCAN, the reading count specifies the
number of readings to store in the buffer. For STEP, the reading count determines the num-
ber of channels to scan.
For SCAN, the reading count also determines the number of scans to perform and is best
explained by an example. Assume there are 10 channels in the scan list (i.e., 101 through
110). If you set the reading count to 10 or less, one scan of the 10 channels will be per-
formed. If you set the reading count to any value from 11 to 20, two scans will be per-
formed. A reading count from 21 to 30 gives you three scans, and so on.
Timer interval (TIMER)
— For the STEP function, the timer specifies the time delay
between scanned channels. For the SCAN function, the interval specifies the time delay
between scans. The timer starts when the scan is started. For SCAN, the next scan will not
start until the timer interval expires.
NOTE
The Model 2701 can also be configured to run an advanced scan. For an
advanced scan, each channel can have its own unique setup (i.e., function,
range, etc.). Advanced scanning is covered in Section 7.
