1.1 Product Overview
MF2412B/MF2413B/MF2414B are microwave frequency counters capable of directly measuring frequency without an
external mixer. The unit also has burst wave carrier frequency measurement and pulse width measurement capabilities that
are indispensable for evaluating circuits and mobile radio communications devices.
This device offers simple operability. With a simple one-step operation on the front panel, you can switch between con-
tinuous wave measurement and burst wave measurement. You can also directly enter a variety of settings from the front
panel including measurement resolution, gate timing for pulse width measurement, and delay time.
The MF2412B/MF2413B/MF2414B are available depending on the available frequency range of input 1 you want to use.
Table 1-1 lists the relationships between the model names and the available frequency ranges and input connector types.

Features
• Measurement of a wide band from 10 Hz to 40 GHz (MF2414B)
• High-speed measurement using a fast counter module
•High-Accuracy burst measurement
•Graphical display
• Built-in template feature (See Note 1)
• Transient measurement (See Note 2)
•GPIB standard unit
Note 1 :
This feature sets, in advance, a frequency range that decides an upper and lower value. If the measured frequency
value is within that range, the unit displays Go, and if it not, the unit displays No-Go. This features will also
output a TTL level high signal or low level signal from the AUX terminal.
Note 2 :
This feature measures the input frequency at a minimum sampling frequency of 10 µ sec without a measurement
pausing time. You can use it to measure VCO start-up characteristics.
