SR280 Mainframe and Display
The SR280 is the Boxcar Averager System mainframe.
The mainframe is NIM (Nuclear Instrumentation Module)
compatible and has twelve slots. The three right-most slots are
filled by the display module and unregulated power supplies,
leaving nine slots for other NIM modules. The DC power
supply regulators are mounted on a heat sink on the rear of
the mainframe.
The display module features three types of meters. The analog
meter is for “peaking-up” an experimental signal. The digital
voltmeter provides a numeric readout. The “Digital Hold”
button may be used to hold the digital meter’s reading. A
20-segment bar graph display may be used to show rapidly
changing data.
