Setting the Pulse Width A & Pulse Width B
Measurement
For a functional description, see 2.4.
Procedure
1.
Press the FUNCTION key to display the Function menu.
2.
Press the Function soft key to display the Function selection menu.
3.
Press the PW&PW soft key.
When the sampling mode is set to inter-symbol interference analysis (ISI), the soft
key is displayed as PW
→
PW.
The following menu appears.
Explanation
Polarity
Only the following setting is available.
A
, B
:
Measures from the rising edge to the next rising edge and from the
falling edge to the next falling edge of the CH A input signal. At the
same time, measures from the rising edge to the next rising edge and
from the falling edge to the next falling edge of the CH B input signal.
Measurement Range of Pulse Width
Varies depending on the sampling mode.
• When in time stamp mode:
6 ns to 20 ms
• When in hardware histogram mode:
6 ns to 3.2
