JK2817N/JK2831/JK2832 Three different types of instruments with different frequency ranges in
the above range according to the minimum frequency and maximum frequency automatically
determine the range.
■ minus -
The soft key is a frequency reduced fine adjustment key. Each time the key is pressed, the
frequency is reduced to the next lower frequency point. Use the soft key to set the frequency point
plus+
■ minus --
The soft key is frequency reduction coarse adjustment key. Each time the key is pressed, the
frequency decreases in the six typical frequency points of the following table. Use the soft key to
set the frequency point plus plus + +.
2)
Choose or set the test frequency using soft keys or numeric input keys. Soft keys display the
currently available frequency units (Hz, kHz, MHz) when the required frequency values are
entered with a digital key. You can use these unit soft keys to input units and data.
Note: If the input frequency is not the frequency supported by JK2817N/JK2811B, it is
automatically corrected above the frequency point nearest to the input frequency.
3.1.4 Test level
The test level of JK2817N /JK2811B is set according to the valid value of the sine wave
signal.The frequency of the sine wave is the test frequency, and is generated by the internal
oscillator of the instrument.You can set the test voltage value.can also set test current value.The
output impedance of the JK2817N/JK2811B signal source can be chosen as 30 Ω or 100 Ω. test
level:0.1V ,0.3V ， 1V ， When the current input mode is used, the maximum current is equal to the
maximum level divided by the internal resistance of the source.
Note: the test current set by JK2817N/JK2811B is the output current value when the terminal is
short circuited.The test voltage set is the output voltage value when the terminal is open.
JK2817N/JK2811B's automatic level control function enables constant voltage or current
measurement.The automatic level control function (constant level domain) can be set from <
measurement Settings > page to ON.When the automatic level control function is turned on, a "*"
number is displayed after the current level value is displayed. For more information, please refer
to the < measurement Settings > page.
