Figure 2-2: Measurement, ACQ, Mode, and MAG Controls
The 370B has three measurement modes, REPEAT, SINGLE and SWEEP.
REPEAT. The REPEAT button causes the Step Generator to generate a repeated
set of step signals and the measurement is performed repeatedly.
SINGLE. The SINGLE button causes the Step Generator t generate one step of
signals and the measurement is performed once. The Collector Supply and the
Auxiliary Supply always provide power regardless of the SINGLE function.
Pressing the SINGLE button while holding down the FAST/SHIFT button
changes the button function to USER REQUEST, which causes the 370B to send
a service request (SRQ) signal over the bus. This alternate function is not printed
below the SINGLE button.
SWEEP. The SWEEP button causes the Collector Supply (or Step Generator) to
automatically sweep the output from the value set by the VARIABLE COLLEC-
TOR SUPPLY control (or Step Generator amplitude + offset) to zero (or offset).
The measurement is performed as step signals are generated repeatedly over the
sweep range.
Sweep mode is available when STORE Display mode is selected.
