1. Denotes warranted specifications, all others are typical. Specifications are valid after a 30-minute warm-up period, and ± 5 °C from annual calibration
temperature�
2. Full scale is defined as 8 vertical divisions. Magnification is used below 5 mV/div. Below 5 mV/div, full-scale is defined as 40 mV. The major scale settings are
5 mV, 10 mV, 20 mV, 50 mV, 100 mV, 200 mV, 500 mV, 1 V�
3� Vertical resolution for 8 bits = 0�4% of full scale, for 12 bits = 0�024% of full scale�
4� 13 GHz DSP enhanced bandwidth not applicable at 5 mV/div�
5. FFT amplitude readings are affected by scope and probe bandwidth limitations and input amplifiers roll-off (e.g. 3 dB roll-off at specified bandwidth of
scope/probe)�
6� The FFT signal to noise ratio varies with volts/division setting, memory depth and use of time or frequency averaging�
7a. Noise is the displayed noise floor. SlewRate is the displayed slew rate of the signal at the threshold crossings. Sample rate = max, sin(x)/x interpolation
enabled�
7b. Measurement threshold = fixed voltage at 50% level.
7c. Time ranges ≤ 10 μs.
8� Values represent time error between two edges on a single channel� Standard deviation value refers to the standard deviation of 256 consecutive
measurements performed using an individual instrument. Reading is the displayed DTMA measurement value. TimeScaleAccy is the oscilloscope’s specified
time scale accuracy�
9. Internal edge trigger mode. Trigger threshold = fixed voltage at 50% level. The slew rate independent value in the formula represents the traditional trigger
jitter�
10. Requires Option 010 user defined function.
11� 11�8 GHz analog bandwidth at 5 mV/div for DSO91304A and DSO91204A models�
12� Typically triggers as low as 5 mV/div sensitivity�
