Measuring Frequency

1Connect the Counter to a power source, and set the

Main ~ Power switch on the back panel to 1 (on).

If the Counter is connected to an AC power source, the Main AC Power indicator on the back panel and the Standby indicator on the front panel

light. If the Counter is connected to an external DC power source or is operated from internal batteries (with Battery option only), the Standby indicator lights, but the Main AC Power indicator does not.

2Press the POWER button on the front panel.

The Standby indicator goes off, and all segments of the front-panel display are temporarily activated. TESTING is displayed while the Counter performs its power-on self-test. If the Counter passes all of the tests, SELF TEST OK is displayed, and the Counter then displays its model number, firmware version number, GPIB address, and CH2 NO SIGNAL. The Counter is now ready to measure the frequency of a signal applied to the Channel 2 input. Note that the Ch 2 and Freq annunciators are activated.

3Connect an input signal to Channel 2.

The Channel 2 input path circuits contain sensitive GaAs semiconductors. To prevent damage to these components, always adhere to standard ESD (ElectroStatic Discharge) prevention procedures, and ensure that the maximum power specification for this channel (+27 dBm) is not exceeded.

The Counter automatically displays the measured frequency of the input signal. To set the resolution, measurement rate, and/or the number of averages, see the appropriate procedure in the section titled “Operating the Counter,” or refer to “Setting the Resolution,” “Setting the Measurement Rate,” and “Setting the Number of Averages,” later in this chapter.
