Performance Requirement
X-Y displays can only be obtained in conjunction with a
time-base unit . With an amplifier unit installed in the
A(B) horizontal compartment the Z-axis can only be controlled
by the time-base unit in the B(A) horizontal compartment.
This is independent of the horizontal mode switch selection.
Positive going, with baseline near 0 volt .
(Selected by front-panel CALIBRATOR switch .)
40 mA available through CALIBRATOR output with optional
bnc-to-Current Loop adapter. CALIBRATOR must be set to
4 V for calibrated output .
500 ns or less into 100 pF or less .
Selected by front-panel switch .
A: A HORIZ time-base unit .
B: B HORIZ time-base unit .
Positive-going with baseline at 0 V within 1 V into 1 Mfl.
50 mV/unit of time selected by time-base unit time/div
switch, within 15%, 100 ns/div maximum sweep rate .
1 V/unit of time selected by the time-base unit time/div
switch, within 10%; 1 ps/div maximum sweep rate .
Selected by front-panel switch .
A : A Gate, derived from A HORIZ time-base unit main gate .
B: B Gate, derived from B HORIZ time-base unit main gate .
