Functional Overview

Inputs A1, A2, A3, and B1, B2, B3 are designed to be used as three-wire inputs for component signals.

A123 / B123

Selecting A123 provides a side-by-side display of the CH-A1,

CH-A2, and CH-A3 inputs (B123 displays the CH-B1, CH-B2, and

CH-B3inputs). This is designed for monitoring component signals.

Parade

Selecting PARADE displays the input channels last selected for PARADE, allowing a custom configuration of inputs. In PARADE mode, the LINE/FIELD button offers only two choices: one line and one field. Up to four channels can be displayed side-by-side; additional channels are overlaid.

Overlay

OVERLAY superimposes the selected input signals. The LINE/ FIELD button remains a four-way toggle, providing one line, two line, one field, and two field displays.

Sweep

Sweep buttons are used to select the waveform sweep rate. LINE/FIELD toggles through four sweep rate selections: one line, two line, one field, and two field. In PARADE mode, the LINE/FIELD button becomes a two-way switch, toggling between line and field.

The sweep rate is displayed in the upper right corner of the CRT (for field-rate sweeps, 1F or 2F is displayed).

The MAG button is used with LINE/FIELD to provide horizontal magnification of each rate as follows:

HOne line magnified = 200 ns/division

HTwo line magnified = 1 µs/division

HOne field or two field magnified = approximately X20 magnification.
