DC~40MHz (-4 dB)
5V/Div:DC~40MHz (-5dB)
1mV~2mV/DIV:
DC~10MHz (-3dB)
AC coupling: Low limit frequency 10Hz.
(With reference to 100kHz, 8 DIV. Frequency response with –3 dB.)
5 mV ∼ 5 V/DIV: ≈ 8.75 ns
1 mV ∼ 2 mV/DIV: ≈ 35 ns

Other distortions and other ranges: 5% added to the above value. (10ºC to 35 ºC)
5 mV ∼ 5 V/DIV: ±0.5 DIV, 1 mV ∼ 2 mV/DIV: ±2.0 DIV
< ±0.1 DIV of amplitude change when waveform of 2 DIV at graticule centre is
CH1: CH1 single channel.
CH2: CH2 single channel.
DUAL: CH1 & CH2 channels. CHOP/ALT are auto-set by TIME/DIV switch.
(CHOP:0.5 s ∼ 5 ms/DIV, ALT: 2 ms ∼ 0.1
When CHOP switch is pushed in, the two traces are displayed in the
CHOP mode at all range.
ADD: CH1 + CH2 algebraic addition.
400 V (DC + AC peak), AC: frequency 1 kHz or lower.
50:1 or better at 50 kHz sinusoidal wave.
(When sensitivities of CH1 and CH2 are set equally)

Bandwidth (-3 dB): OD-514B: 20 MHz, OD-515B & OD-545B: 40 MHz
Balanced point variation: ≤ 1 DIV (Reference at centre graticule.)

CH1, CH2, LINE, EXT (CH1 and CH2 can be selected only when the vertical
mode is DUAL or ADD). In ALT mode, if the TRIG. ALT switch is pushed in, it can
be use for alternate triggering of two different source. )
