Performance Characteristics
* Denotes Warranted Specifications, all others are typical. Specifications are valid after a 30-minute warm-up period, and ±10°C (models 54810A/15A/20A/25A) or
±5°C (models 54835A/45A) from firmware calibration temperature.

Memory Depth Modes
Auto: Optimized for best combination of update rate and display quality.
Manual: Selectable from 16 to 32,768 points Selectable
2 channel mode: from 16 to 65,536 points
4 channel mode: from 16 to 32,768 points
Sampling Modes
Real Time: Successive single shot acquisitions.
Equivalent Time: Random Repetitive sampling (higher time resolution at faster sweep speeds)
Peak detect: Captures and displays narrow pulses or glitches n/a
1 ns or wider at sample rates of 250 MSa/s or less
Filters:
9-bit Bandwidth Limit Filter: BW = Sample Rate/20
(Sinx)/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
Averaging Selectable from 2 to 4096
