Mask testing
Allows pass/fail testing to user-defined or Keysight-supplied waveform templates. Automask lets you create a mask
template from a captured waveform and define a tolerance range in time/voltage or screen divisions. Test modes
(run until) include test forever, test to specified time or event limit, and stop on failure. Executes “multipurpose”
user setting on failure. “Unfold real time eye” feature will allow individual bit errors to be observed by unfolding a
real time eye when clock recovery is on. Communications mask test kit option provides a set of ITU-T G.703, ANSI
T1.102, and IEEE 802.3 industry-standard masks for compliance testing.

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. FFTamplitudereadingsareaffectedbyscopeandprobebandwidthlimitationsandinputamplifiersroll-off(e.g.3dBroll-offatspecifiedbandwidthofscope/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.
