Sensitivity
1mV ~ 5V/DIV, 12 steps in 1-2-5 sequence
Sensitivity accuracy
5mV ~ 5V/DIV:
≤3%, 1mV ~ 2mV/DIV: ≤5% ( 10℃ to 35℃(50℉ to 95℉) )
<< 5 DIV at the center of display>>
Vernier vertical sensitivity
To 1/2.5 or less of panel-indicated value.

1mV~2mV/DIV:DC~10MHz
5mV~5V/DIV : DC~50MHz,
1mV~2mV/DIV:DC~15MHz
Frequency bandwidth (-3dB)
AC coupling: Low limit frequency 10Hz (With reference to 100kHz, 8DIV. Frequency response with -3dB.)
Rise time

Input impedance
1M ohm ±2% // Approx. 25pF
Square wave characteristics
Overshoot :
≤ 5% (At 10mV/DIV range ) << 5 DIV at the center of display>>
Other distortions and other ranges: 5% added to the above value ( 10℃ to 35℃ (50℉ to 95℉) ).
DC balance shift
5mV ~5V/DIV: ±0.5DIV, 1mV ~ 2mV/DIV: ±2.0DIV
Linearity
< ±0.1 DIV of amplitude change when waveform of 2 DIV at graticule center is moved vertically.
Vertical modes
CH1 : CH1 single channel.
CH2 : CH2 single channel.
DUAL
: CHOP/ALT are auto-set by TIME/DIV switch(CHOP:0.5s~5ms/DIV, ALT:2ms~0.1μs/DIV).
When CHOP switch is pushed in, the two traces are displayed in the CHOP mode at all range.
ADD
: CH1 + CH2 algebraic addition.
Chopping repetition frequency
Approx. 250kHz
Input coupling
AC, DC, GND
Maximum input voltage
400V (DC+AC peak), AC: frequency 1kHz or lower.
When set probe switch at 1:1, the maximum effective readout is 40Vpp (14Vrms at sine wave),
or set probe switch at 1:10, the maximum effective readout is 400Vpp(140Vrms at sine wave).
Common mode rejection ratio
50:1 or better at 50kHz sinusoidal wave. (When sensitivities of CH1 and CH2 are set equally)
