To Make Phase Measurements
Press Other Meas key until
PHASE 1 TO 2
is displayed.
PHASE 1 TO 2
is momentarily displayed, the Ch1 and Ch2 annunicators
light, and the Counter is ready to measure the phase of a signal applied to
CHANNEL 1 input relative to a signal applied to CHANNEL 2 input.
The phase difference is displayed in degrees. If auto triggering is enabled,
the trigger levels are set to the 50% points of each signal. However, you
may disable auto triggering, and change the trigger levels and slopes.
Use CHANNEL 2 as the reference. One period on CHANNEL 2 will
define 360°. If CHANNEL 1 is leading CHANNEL 2, the pulse result is
positive.
To Measure Positive/Negative Voltage Peaks
Press Other Meas key until
VOLT PEAKS 1
or
VOLT PEAKS 2
,
depending on which measurement you want to make, is displayed.
VOLT PEAKS 1
or
VOLT PEAKS 2
is momentarily displayed, the Ch1 or
Ch2 annunciator lights, and the Counter is ready to measure minimum
and maximum voltage peaks of signals applied to CHANNEL 1 or
CHANNEL 2, respectively.
NOTE
In Voltage Peaks function, the Counter measures the input signal after
the signal has been conditioned by the input settings (impedance,
coupling, attenuation, and filter). One reminder of this is the
(
AC COUPLED
) message, which is displayed when Voltage Peaks is
selected and the measurement channel is ac coupled.
The result is corrected for X10 attenuation.
Note that Arming is not used for Voltage Peaks measurements, and that
neither Limits nor Math is available.
