7.3 Performance Test
When performing the performance tests discussed below, warm up the unit to be tested and the measuring equipment for at
least 30 minutes unless directed otherwise and wait for it to stabilize before proceeding with testing. To achieve maximum
measurement sensitivity, you must also perform tests at room temperature and make sure there is little fluctuation in the AC
power supply and that there is not a harmful amount of noise, vibration, dust, or humidity.
7.3.1 Continuous Frequency Measurement
7.3.1.1 Continuous Frequency Measurement on Input1
(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
• Measurement accuracy
Count mode Normal (direct count) :
± count ± time base accuracy × measurement frequency ± residual error 1
Note: residual error1 = {measurement frequency (GHz)/10 count (rms)}
Count mode Fast (reciprocal)
± count ±
time base
accuracy
×
measurement frequency ± residual error 2 ± trigger error
Note: residual error2 = {measurement frequency (GHz)/2 count (rms)}
(2) Test equipment
• Signal generator
• Power meter
•Power sensor
(3) Test procedure
1) Set the unit to preset values. To perform a test in Normal mode, switch the count mode setting.
2) Connect the Reference Output terminal on the back of the unit to the external standard input on the signal genera-
tor.
3) 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) Disconnect the measurement cable you connected to the unit’s Input1 connector, change the output frequency of
the signal generator, repeat steps 3) to 6), and check that frequency is properly displayed within the specified
range.
