Common Mode Rejection Ratio: 50:1 or better at 50 kHz sinusoidal wave. (When sensitivities of
CH1 and CH2 are set equally).
Isolation between channels:
(At 5mV/DIV range)
>1000:1 at 50 kHz.
>30:1 at 30 MHz
CH1 signal output: At least 20 mV/DIV into a 50 Ω terminal,
Bandwidth is 50 Hz to 5 MHz at least
CH2 INV BAL. Balanced point variation: ≤ 1 DIV (Reference at center graticule).
Triggering
Triggering source: CH1, CH2, LINE, EXT (CH1 and CH2 can be selected only in the
DUAL or ADD vertical mode).
In ALT mode, if the TRIG. ALT switch is pushed in, it can alternate
triggering of two different source.
Coupling: AC: 20Hz to full bandwidth.
Slope: + / -.
Sensitivity: 20 Hz ~ 2 MHz : 0.5 DIV, TRIG-ALT: 2 DIV, EXT : 200mV.
2 ~ 30 MHz : 1.5 DIV, TRIG-ALT: 3 DIV, EXT : 800mV.
TV : Sync pulse more than 1 DIV (EXT: 1V).
Triggering modes: AUTO: Sweeps run in the free mode when no triggering input
signal is applied.
(Applicable for repetitive signals of frequency 25Hz or
over.).
NORM: When no triggering signal is applied, the trace is in the
ready state, but is not displayed.
TV-V: This setting is used when observing the entire vertical
picture of television signal.
TV-H: This setting is used when observing the entire horizontal
picture of television signal.
(Both TV-V and TV-H synchronize only when the synchronizing
signal is negative)
EXT Triggering Signal Input
Input Impedance: approx.: 1 Mohm // approx. 25 pF.
Max. Input Voltage: 300 V (DC+AC peak), AC: Frequency not higher than 1 kHz.
