The following step will show you how to update:
(1) At power on, place the U-disk on USB device port, generator will identify it
automatically and prompt a “Di” sound once it successfully connected.
(2) Press〖Utility〗softkey to enter into the utility interface. Press〖System Update〗key
and input the password 0.-123456 to enter into the file manager.
(3) Select Removable Disk A in manager and .exe file. The further operation refers to
chapter 5.16.8. Then select〖System Update〗to pop up the confirm window. If you
select confirm, the generator will start updating and then restart with new firmware.
If you select cancel, the generator will exit and operate with original firmware.
(4) Note: make sure that the updating always at power on, once cut off the power, the
generator will fail to update and restart, which need to return to factory for repair.
5.17 Frequency Counter
Press 【Counter】key to enter into counter menu.
Connect the external measured signal to ‘Counter’ connector on rear panel, then to
measure the frequency, period, pulse width and duty cycle of measured signal.
5.17.1 Continuous Signal
The waveform generator can measure the frequency, period, pulse width and duty cycle
of measured continuous signal. Use multi-cycle measurement when high frequency to
get a accurate result.
Press 〖Freq〗softkey then select ‘Frequency’ to measure frequency of measured signal.
Press 〖Period〗softkey then select ‘Period’ to measure period of measured signal.
Press 〖Width〗softkey then select ‘Width’ to measure pulse width of measured signal.
Press 〖Duty Cyc〗softkey then select ‘Duty Cyc’ to measure duty cycle of measured
signal.
5.17.2 Non-continuous Signal
Non-continuous signal, take a burst signal for example, is not available for the
measurement of frequency, period, pulse width and duty cycle but only for measurement
of cycle number.
Press 〖Count On/Off〗softkey then select ‘On’ to enable the counter. Firstly clear the
count value then totalize count begins. Select ‘Off’ to disable the counter. To get a
accurate measurement, turn counter off when disable the input signal.
Once turn on counter, the setting of gate time is ignored.
