Frequency Response (—3 dB bandwidth)
—10°C to 35°C
Within + 2%.
Within + 3%.
DC to 100 MHz {at the probe tip).
35°C to 55°C DC to 90 MHz (at the probe tip).
Step Response (5-division step)
Rise Time
— 10°C to 35°C 3.5 ns or less.
35°C to 55°C 3.9 ns or less.
Delay Match (CH 3 to CH 4) Less than 800 ps difference.
Trace Shift Between VOLTS/DIV Settings | 1 division or less.
At least +11 divisions from graticule center.
Position Range
Channel Isolation
{attenuation of deselected channel) 34 dB or more at 100 MHz.
Channel isolation tested with eight-division input signal.
Input Characteristics
Resistance TMQ +1.0%.
Capacitance 20 pF 4.0: pF.
Max Input Volts IN 400 V (dc + peak ac}; 800 V p-p ac at 10 kHz or less.

| Linearity is measured by positioning a two-division test signal any-
where on screen and noting the amplitude change.
TRACE SEP Control Position Range At least +4 divisions.
CHOP Mode Clock Rate 625 kHz + 10%.
Delay Match (CH 1 or CH 2 to CH 3 or CH 4) Less than 200 ps difference.
