SourceB can only be set to an analog channel (or digital channel).
4. Phase Measurement Setting
Specify source A and source B in the measurement items “Phs A
→B ”, “Phs
A
→B ”, “Phs A →B ” and “Phs A →B ”.
Press Measure  Setting  Type  “Phase” and then press SourceA and
SourceB to set the two channel sources (CH1, CH2 or any channel of D0-D15)
of phase measurement respectively.
Note: When SourceA is set to any analog channel (or digital channel),
SourceB can only be set to an analog channel (or digital channel).
5. Threshold Measurement Setting
Specify the upper limit, lower limit and middle value of the auto measurement of
the analog channel. Measurements of all the time, delay and phase parameters
will be influenced by this setting.
Press Measure  Setting  Type  “Threshold” and then:
 Press Max and use to set the maximum value of the measurement.
Reducing the maximum value to the current “Mid” will automatically reduce
“Mid” (“Min” might also be included) to keep it (them) lower than the
maximum value. The default is 90% and the range available is from 7% to
95%.
 Press Mid and use to set the middle value of measurement. The middle
value is limited by the settings of “Max” and “Min”. The default is 50% and
the range available is from 6% to 94%.
 Press Min and use to set the minimum value of the measurement.
Increasing the minimum value to the current “Mid” will automatically
increase “Mid” (“Max” might also be included) to keep it (them) higher than
the minimum value. The default is 10% and the range available is from 5%
to 93%.
