Notes
CAT I and CAT II Definitions
Installation category (overvoltage category) I: Signal level, special equipment or parts of
equipment, telecommunication, electronic, etc., with smaller transient overvoltages than
installation category (overvoltage category) II.
Installation category (overvoltage category) II: Local level, appliances, portable equipment etc.,
with smaller transient overvoltages than installation category (overvoltage category) III.
Video Output 15-pin VGA, full color.
1 Rise Time figures are calculated from: tr=.35/Bandwidth.
2 Magnification is used below the 10 mV/div range and between the major attenuation settings. Full scale
is defined as the major attenuator setting over an intermediate setting.
(Major settings for 50
Ω
: 10, 20, 50, 100, 200, 500, 1000 mV
Major settings for 1 M
Ω
: all as for 50
Ω
plus 2 V)
3 N/A
4 For bandwidth limited signals, tr >=1.4 x sample interval.
5 FFT amplitude readings are affected by input amplifier roll-off (-3 dB, with amplitude decreasing as
frequency increases above 500 MHz in 1 M
Ω
, 2.25 GHz for Agilent 54846A, 1.5 GHz in 50
Ω
for Agilent 54845A,

Ω
for Agilent 54835A).
