370B User Manual
The STEP GEN OUT connector allows the Step Generator output to be used
externally. The EXT BASE or EMITTER IN connector allows application of an
externally generated signal to either the base or the emitter of the device under
test. The external signal is applied to whichever terminal is chosen by the
CONFIGURATION switches. The AUX SUPPLY OUT connector supplies the
auxiliary voltage to external.
Table 3–3 shows the polarities of the Collector Supply and the Step Generator
output for various settings of Collector Supply POLARITY and CONFIGU-
RATION.

The digital storage mode displays acquired characteristic curves with a bright,
flicker-free trace. This mode digitally stores characteristic curves in the internal
memory, converts the curves to analog signals, and displays them on the CRT.
The mode is activated by pressing STORE. The NON STORE/STORE/VIEW
INTENSITY control adjusts the store intensity. The resolution of acquisition is
100 points/division in both axis.
The 370B has two ACQUISITION modes (STORE MODE), AVERAGE and
ENVELOPE. In AVERAGE mode, acquired curves are averaged and displayed
on the CRT after calculation. A running count of the acquisition is displayed on
the CRT.
After the acquisition count exceeds 16, the 370B continues the averaging but
acquisition count stops incrementing.
