13.1 System Function
(1)
Automatic Calibration
Automatic calibration allows the oscilloscope to work optimally to obtain the most accurate
measurements. Automatic calibration divide into analog channel calibration and LA calibration. This
function can perform at any time, especially when the ambient temperature range reaches or exceeds
5
℃
. Before performing the automatic calibration operation, make sure that the oscilloscope is
operating for more than 20 minutes.
a.
Analog channel calibration
：
Only calibrating analog channel and calibrating time about 3
～
5min.
b.
LA calibration
：
Only calibrating digital channel and calibrating time about 3
～
5min.
(2)
System Information
System Information can view the system information of the oscilloscope, which includes model, SN
number, software version number, hardware version number, FPGA version number, manufacturer and
website’s QR code.
(3)
Language
Language can set system language to English, simplified Chinese. By default, language display is the
current setting.
(4)
Interface Setting
Interface menu can set menu display time and transparency of pop out dialog. Menu display time can
set to 5s, 10s, 20s or manual. The default setting is manual.
(5)
Square Output
Square Output can set the output frequency of local square waveform, which can set to 10 Hz, 100 Hz, 1
kHz or 10 kHz. The default setting is 1 kHz.
(6)
Frequency Meter
Frequency Meter can set the state of frequency meter (on/off). Source can set to CH1~CH4 or trigger
source. When the frequency meter is enabled, source and frequency meter information in Freq pop out
dialog will display on the top of the screen. When the frequency meter is disabled, Freq pop out dialog
will disappear. Frequency meter is the counter of trigger event frequency in the trigger channel, display
as hardware 7 digitals frequency meter.
(7)
AUX Output Selection
Output Selection set which signal can output via AUX OUT port, it can select “trigger “or pass/fail test.
When “trigger” is selected, AUX OUT port exports trigger synchronizing signal. When “pass/fail test” is
selected, AUX OUT port exports the output signal of pass /fail test. The default setting is “trigger”.
(8)
Automatic Setting
Auto can set hold or auto mode. Hold which is keep the setting before AUTO; AUTO which is freely to set
and not keep the setting, such as channel setting, sampling setting, trigger setting and active channel.
a.
Channel setting
：
In hold mode, remain the bandwidth limit and inverse phase, restore coupling
（
ground
）
and volts/div scale to the default value.
b.
Sampling setting
：
In hold mode, remain the sampling mode and average time, restore the storage
