These connectors provide the input and output ports for the
instrument's timebase reference. The instrument will lock to
a 2 MHz,
5 MHz, or 10 MHz external reference source connected to the input
that is within
f5 ppm. When the internal timebase is being used, the
output connector provides a
10 MHz, 1 Vrms level signal.
This knob controls the front-panel display contrast. Display contrast
can be optimized for viewing the display from above, below, or
directly in front
of it.
