155
Set the span to a minimum span of 1 kHz.
[Span Pre]
Set to the previously selected span value.
[Start Freq]
Activate start frequency and set to the start frequency/stop frequency mode. The starting frequency can
be adjusted with the figure keys, step keys or the rotary knob, and step keys and the rotary knob change
based on the step frequency. If the set start frequency exceeds the stop frequency, the start frequency is
automatically set and its value is equal to the stop frequency -1 kHz.
[Stop Freq]
Activate stop frequency, and set it to the start frequency/termination frequency mode. The stop
frequency can be adjusted with the figure keys, step keys or the rotary knob, and the step keys and the
rotary knob change based on the step frequency. If the set stop frequency is less than the start frequency,
the frequency is automatically set and its value is equal to the start fre1 kHz.
[Step Freq Auto Man]
Adjust the frequency step. When this function is automatic mode and the center frequency is activated,
press the step key once, the center frequency changes by one frequency step value, and the default
frequency step value is 1MHz. In manual mode, the step frequency can be adjusted with the figure keys,
step keys or rotary knob. At this time, activate [Center Freq] again, press the step key, and the center
frequency will change with the set step size.
【
Amplitude
】
Pop-up amplitude function-related menu, including [Ref Level], [Auto Scale], [Max], [Min], [Relative Off
On], [Offset], [Preamplifier Off On ].
[Ref Level]
Activate the reference level setting function, the default is 0dBm. The reference level can be adjusted
with the figure keys, step keys or the rotary knob. Set step a
mplitude
to
1 dBm
. The accuracy of the
measurement signal at the reference level position is best. The internal input attenuator is associated
with the reference level and can be automatically adjusted to avoid compression of the input signal.
[Auto Scale]
It is used to display the maximum and minimum values of the panel, so that it is most suitable for
displaying the current power. The maximum value is displayed as the current power value +7dB, and the
minimum value is displayed as the current power value -3dB.
[Max]
It is used to adjust the maximum value of the display panel.
[Min]
It is used to adjust the minimum value of the display panel.
[Relative off on]
When the relative measurement switch is turned on, the microwave analyzer will measure and store the
current power level, while the power measurement will show a power level relative to the saved value.
When the relative measurement is turned on, the unit switches from dBm to dB or Watts to %.
[Offset off on]
Set the offset value. A positive value compensates for the loss and a negative value compensates for the
gain.
[Pre Amp Off On]
It is used to turn the preamplifier on or off.
【
BW
】
Pop-up menu for setting bandwidth and averaging, including [RBW Auto Man] , [VBW Auto Man] ,
