3-4. Period Measurements
a. Apply the signal to be measured to the input A BNC.
b. Select the degree of resolution desired, using the gate time switch.
c.Period is given by the display. The gate indicator lights while each
measurement is in progress.
d. attenuator, low pass fitter, coupling switch application is same as
frequency measurements mode.
3-5. Total Measurements
The totalize mode is used to count the total number of events occurring during
a specific time period. Maximum frequency is 30 MHz.
a. Set the totalize mode. Any gate and units setting is ignored.
b. Apply the signal to be measured to input A , and then the counter display
is the count continually. Maximum count is 999999999. if this is exceed
the overflow message display as ”OF”
c. Low pass filter and attenuator, coupling switch application is same as
frequency measurements mode.
NOTE
THE HOLD SWITCH MAY BE USED TO BE LATCH THE DISPLAY. HOWEVER, THE
COUNTER TO INCREMENT AND WHEN THE HOLD IS RELEASED, THE UPDATE
COUNT IS DISPLAY.
3-6. RPM (Rotation Per Minute) Measurement <FC-3000, FC-7150, FC-7015>
a. Apply the signal to be measured to the input A BNC, and then the
counter displays the RPM. Maximum count is 999999999. If this is
exceed, the overflow message displays as ”OF”
b. Low pass filter and attenuator, coupling switch application is same as
frequency measurements mode.
3-7. Time Interval Measurements(A→B) <FC-7150U, FC-7015U>
In time interval mode, unit measures the elapsed time from a selected edge of the
input A waveform to a selected edge of the input B waveform. For a stable reading, the
two input signals should be related to each other such that this time interval remains
reasonably constant from one measurement to the next. For example, two digital
waveforms derived from the same clock would be suitable; two arbitrary frequencies
from separate function generators would not.
