Specifications & characteristics
The following tables list the performance specifications and operating characteristics for the
Agilent Technologies 54835A/45A/46A oscilloscope. Asterisks (*) denotes warranted
specifications, all others are typical. Specifications are valid after a 30 minute warm-up period,
and within
± 5 °C from the self-calibration temperature.

Sampling Modes Real Time Successive single shot acquisitions.
Equivalent Time Random repetitive sampling (higher
time resolution at fast sweep speeds).
Filters 9-bit Bandwidth Limit filter: BW = (Sample Rate)/20
(Sin x)/x Interpolation: On/Off selectable FIR digital filter. Digital signal
processing adds points between acquired data points to enhance
measurement accuracy and waveform display quality.
BW= Sample Rate/4
