13.2 Measurement Function
Item
Specifications
Measurement update rate
†
Minimum 50 ms (when measurement function is D-to-C jitter, data signal slope is both rising and
falling, and the gate time is 30 ms)
However, it is 2 ms when D-to-C high speed calculation
††
is ON:
Pulse width jitter
Measuring range (upper and lower limit range of the pulse width to be measured)
Setting range for pulse width lower limit: 0.00 to 998.99 ns, setting resolution 0.01 ns
Setting range for pulse width upper limit: 1.00.00 to 999.99 ns, setting resolution 0.01 ns
D-to-C jitter (phase difference between the data and clock signal)
Setting range: 0 to T ns (T: clock period), 0 to 20% (jitter ratio)
D-to-C jitter excluding 2T
‡
Setting range: 0 ns to Tns (T: clock period), 0 to 20% (jitter ratio)
Level measurement
Measuring range: 100 mVp-p to 2 Vp-p (3 mVp-p resolution)
Measurement accuracy:
±
(5%+10 mV) (for measurement of amplitude 1 Vp-p, 100 kHz
sinewave)
†
Measured value under standard operating conditions as described in General Specifications after the warm-up time has
elapsed.
††
The D-to-C high speed calculation function is not available on products with suffix code -BDS.
‡
D-to-C jitter excluding 2T cannot be measured by products with suffix code -BDS.
