A.4.3. SCA Sweep Control

This control provides an efficient method for choosing the optimum SCA settings without
resorting to an oscilloscope. An SCA window (with a width of 19.5 mV between upper and
lower levels) is swept from 0 to +10 V as the MCS scans through a pass length of 512 channels.
The resulting histogram displays the pulse-height spectrum presented at the SCA Input. By using
the cursor to mark a region over the feature of interest in the spectrum and clicking the mouse on
the Set SCA button, the SCA levels are automatically set at the upper and lower limits of the
selected region. This is a quick and accurate method for setting up the SCA for a conventional
MCS scan. A single pulse height scan lasts 5 to 20 seconds, depending on the speed of the com-
puter. To improve the counting statistics in the histogram, scans are automatically repeated until
the acquisition is stopped, or the SCA levels are set.

A.4.4. Pass Control

Acq Mode: Sum, Replace, Rep/Sum The alternatives for data acquisition are selected via
three displayed buttons. See Acquisition Modes in Section A.1.

Trigger: Internal, External Two displayed buttons control whether the Start Output from the
MCS will trigger the external instruments for the start of each scan (Internal Trigger), or a Start
Input from the external instruments will start each scan (External Trigger).

Pass Length Data entry box, with up/down arrows for adjustment, selects the number of chan-
nels in a single pass (scan) from 4 to 65,536 with ramp output active or inactive.

Pass Count Preset Data entry box, with up/down arrows for adjustment, selects the number of
passes that will be executed before data acquisition automatically stops. Selectable from 1 to
4,294,967,295 passes. or OFF to disable.

Dwell Two displayed buttons permit selection of the Internal dwell-time clock or an External
channel advance input. The Bin Width data entry box provides selection of a range of internal
dwell times. See Dwell Time in Section A.1. A data entry box permits adjustment of the external
channel advance input Threshold from –1.6 to +3 V in 1.5 mV steps (minimum pulse amplitude
30 mV).

A.4.5. Ramp Control

Style: Begin-End, Begin-Mid-End Two displayed buttons select either a single-segment ramp
or a two-segment ramp. The single-segment ramp moves linearly from the specified starting
voltage at the beginning of each pass to the specified ending voltage at the completion of each
pass. The two-segment ramp makes a linear transition from the specified starting voltage at the
beginning of the pass to a specified Mid voltage at the mid-point of the pass. It makes another
