DC coupling position.
3-3-2
INPUT C (80 MHz to 2.4 GHz)
CAUTION
THE MAXIMUM INPUT LIMIT TO THIS INPUT IS 3 Vrms MAXIMUM OVER
THE INPUT FREQUENCY RANGE. THE X 10 ATTENUATOR DOES NOT
APPLY.
a. Apply the signal to be measured to the input C. BNC.
b. Set the function indicator to the FREQ. C position.
c. Select the degree of resolution desired, using the gate time switch.
d. Frequency is given by the display. The indicator lights while each
measurement in progress.
e. Engaging the hold switch “freezes” the display at the existing reading,
When hold is released, the display is updated and resumes counting.
f. The attenuator and LPF coupling switch have no effect in input C.
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 measurement 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.
