Settling Times
Average-only mode
In normal and x 2 speed, manual filter, 10 dB decreasing power step refer to Table 12.
Table 12. Settling time (average only mode).
Number of average 1 2 4 8 16 32 64 128 256 512 1024
Settling time(s) normal 0.08 0.13 0.24 0.45 1.1 1.9 3.5 6.7 14 27 57
Settling time(s) x 2 0.07 0.09 0.15 0.24 0.45 1.1 1.9 3.5 6.7 14 27
In fast speed, within the range –50 to +20 dBm, for a 10 dB decreasing power step, the settling time is
10 ms (for the E4416A) and 20 ms (for the E4417A).
When a power step crosses the power sensor’s auto-range switch point, add 25 ms.
Normal mode
In normal, free run acquisition mode, within the range –20 to +20 dBm, for a 10 dB decreasing power
step, the settling time is dominated by the measurement update rate and is listed in Table 13 for various
filter settings.

In normal mode, measuring in continuous or single acquisition mode, the performance of rise times, fall
times and 99% settled results are shown in Table 14. Rise time and fall time specifications are for a
0.0 dBm pulse, with the rise time and fall time measured between 10% to 90% points and upper range
selected.

Table 14. Rise and fall times versus sensor bandwidth.
1
Overshoot in response to power steps with fast rise times, i.e. less than the sensor rise time, is < 10%.
When a power step crosses the power sensor’s auto-range switch point, add 10 µs.
1 Rise and fall time specifications are only valid when used with the E9288A sensor cable (1.5 meters).
