7.3.2 Burst Wave Carrier Frequency Measurement
(1) Test specifications
•Frequency range 600 MHz to 20 GHz ................ MF2412B
600 MHz to 27 GHz ................ MF2413B
600 MHz to 40 GHz ................ MF2414B
• Input sensitivity –33 dBm : ................................ <12.4 GHz
–28 dBm : ................................ <20 GHz
–25 dBm : ................................ <26.5 GHz
{0.741 × f (GHz) –44.6} dBm :≤ 40 GHz
• Pulse width 100 ns....................................... Burst width Narrow
• Measurement accuracy
± 1 count ± time base accuracy × measurement frequency ± trigger error ± residual error 2
± 1/T
GW
Note : residual error2 = {measurement frequency (GHz)/2 count (rms)}
TGW = Gate width
(2) Test equipment
• Signal generator capable of pulse modulation or a signal generator and pulse modulator
• Power meter
•Power sensor
(3) Test procedure
1) Set the unit to preset values and then make the following settings:
Pulse width : Narrow
Measurement resolution : 1 MHz
Frequency acquisition mode : Manual
Manual frequency : Output frequency of signal generator
2) Connect the Reference Output terminal on the back of the unit to the external standard input on the signal genera-
tor.
3) Set signal generator output to continuous wave (pulse modulation Off), and then use a measurement cable to
connect the signal generator output connector to the power meter input connector.
4) Adjust the signal generator output level to the rated sensitivity of the power meter.
5) Disconnect the measurement cable you connected to the power meter input connector and connect it to the unit’s
Input1 connector.
6) Check that the output frequency of the signal generator is being displayed on the counter.
7) Sets the pulse modulation width to 100 ns, continuous period to 500 ns, and turn pulse modulation On.
8) Set the unit’s Meas Mode to Burst.
9) Check that the output frequency of the signal generator is being displayed on the counter.
10) Disconnect the measurement cable you connected to the unit’s Input1 connector, change the output frequency of
the signal generator, repeat steps 3) to 9), and check that frequency is properly displayed.
