or the
knob, and the step of frequency change is 10 MHz.
·[Special Attention]: The frequency setting range is related to the selected USB
power probe, and the specific range is shown in Table 6-1.

switch the display accuracy of measurement data. 0 means only integers are displayed,
1 means 1 decimal place is remained, 2 means 2 decimal places are remained, and 3
means 3 decimal places are remained.

range of 10 dB.
·[Max Value]: Press
【

or the knob, and the default step of change is 1 dB.
·[Min Value]: Press
【

→[Min Value]. It is the minimum value of the current
display signal and can be changed by using the numeric keys, or by using
【 ↑ 】 【 ↓ 】
or the knob, and the default step of change is 1 dB.
·[Relative Off On]: Press
【
Ampt
】 →[Relative Off On]. The relative measurement
function reflects the power change that the reference signal has been set. The readings
of the changes of power values are expressed in dB and %. When the relative
measurement is on, the instrument will measure and save the current power level while
the Power meter will display a power level relative to the saved value.
·[Offset Off On]: Press
【
Ampt
】
→[Offset Off On]. When the power of the measured
piece is greater than the maximum power to be measured by the instrument, the
measured power can be reduced to the normal measuring range by connecting an
attenuator. The power offset function can set the offset value to offset the attenuation
value of the added attenuator or losses of connecting cables. It may also set the power
offset to increase the gain of the amplifier. Positive values compensate for losses, and
negative values compensate for gains.
·[Max Hold Off On]: Press
【
Ampt
】 →[Max Hold Off On] and turn on the maximum
hold signal to display the maximum value of the measurement.
