5.1.2 Start-Up
•
Check conductors of the A, B and C channels in good condition
•
Connect the AC power cable to the recess power receptacle and plug it into three-contact electrical outlet
•
Turn on the Power switch of DPS
•
Turn on the Power switch of U/C located on the rear panel. In this case, all segments, PASS-ALL and UC-1300
shall be displayed as a self test.
•
Set the display Option key (28) at U/C position.
•
Set the Gate time switch (4) at 1 S position.
•
Set the Channel Select Switch (3) at Channel A position.
•
Set the Data-Hold Switch and the Attenuation Switch at the pushed-out position. Now, "GATE" "0.0000000"
"MHz" is lit up at frequency LED display.
5.1.3 Features
Channel Select Switch (3)
The Channels A and B will cover your measurement of the frequency from 5 Hz up to 100 MHz with auto range. The
Channel C will cover your measurement of the frequency from 100 MHz up to 1.3 GHz.
Gate Time Switch (4)
For a better resolution in your measurement, your selection for a proper gate time is advisable. The following table
will help you refer to the optional frequency resolution.

Data-Hold Switch (5)
Upon activation of this mode, a read-out on the LED display will be captured and remained even after disconnecting
the test connector from a measuring point.
Attenuation Switch (2)
If input signal is greater than 700 mV, set the Attenuation Switch at the pushed-in position with connecting the input
signal to channel A only.
The triggering sensitivity of the input signal will be decrease by 1/10 (-20 dB) and reduce errors.
Reset Switch (6)
If you want to return to the normal frequency mode from the arithmetic modes, set FREQ switch at the pushed-in
position.
5.1.4
Mesuring the output frequency generated by F/G
If you want to measure the output frequency being measured by the function generator, set the display option key
(28) at F/G position.
