1. By pushing , the SPRIOUS FREE mode, by which the spurious response at band 1- and band 1+ is simply deleted, is selected. * “SPR” is displayed in CALC area on the screen. (Refer to “4. Explanation of Screen” for the details.)

• Differing from base band at which the up-conversion of input frequency is done with a frequency mixer, the spurious response peculiar to band 1- and band 1+ is generated because the down-conversion is done at those two bands. * About SPURIOUS FREE mode 1. SPURIOUS FREE mode is a mode by which the spurious response peculiarly caused at band 1+ is simply deleted. 2. SPURIOUS FREE mode is especially effective in the measurement of a stationary wave. 3. If SPURIOUS FREE mode is used in measurement of a signal with level change or frequency change, the phenomenon that the level goes down will occur. 4. The noise level goes down a little in case of a noise changing at random. In short, the same phenomenon as MIN HOLD function happens. * How to judge SPURIOUS response at band 1- and band 1+ The procedure for judging SPURIOUS response at band 1- and band 1+ is as follows. 1. Set the center frequency to < (current setting value) + f >. 2. The spectrum shifting left by f is a correct spectrum, but another spectrum shifting such as left by 2f, left by 3f, right by f, right by 2f or right by 3f is a spurious response. * “f ” should be changed according to SPAN for easy judgment. For reference; f = SPAN / (10 to 50) (corresponding to 0.2 to 1 div) Example: judging a spectrum displayed at 6.92 GHz (setting : center frequency 6.92 GHz and SPAN 500 MHz) 1. Set the center frequency to < 6.92 GHz + 500 MHz/25 > = 6.94GHz. right by 2f from 6.94 GHz) is spurious. * Additionally, a spurious response mentioned above shifting right by 2f at band 1+ is largest, and other spurious response are about 25 to 50 dB smaller than that. 17.

25.8 Writing of Original Compensation Data

When antennas or probes other than the option is used in electric field strength measurement or magnetic field strength measurement, it is necessary to write each original compensation data into the unit. Please write the data into the unit according to the following description. There are two methods for writing. Either use the 2650A PC Software or write a custom program using interface commands. 1) Preparation items * Windows PC (with USB interface) [The writing can be done with 2650A/2651 series unit only.] * 2650A PC software (Refer to 3) below) 2) Example of writing data As an example, the compensation data (antenna gain) of antenna M405 and the compensation data (compensation coefficient) of magnetic field probe CP-2S are shown below. * Compensation data (antenna gain) of antenna M405 Frequency 300MHz 350MHz 400MHz 450MHz 500MHz * Compensation data (compensation coefficient) of magnetic field probe CP-2S Frequency 10MHz 100MHz 1GHz 2GHz 3GHz Compensation * Data of ten points or less can be written. 0Hz is not valid as a data point. 3) Using 2650A PC software for writing 1. Create the text file of compensation data.

Create a new text file, and open it with a text editor. Write the frequency and compensation data in the following format. * Format “frequency”: ”compensation data”, “frequency”: “compensation data”, · · · Example of M405 * Write the unit with a capital letter as it is case sensitive. G (GHz) is also available. 2. Write the text file into the unit with 2650A PC software. Connect the personal computer to 2650A series with the included USB cable and turn on the power of the 2650A/2651 series. From the upper menu of the PC software, select [File] → [Write E/F User Data] in case of electric field strength measurement, or select [File] → [Write M/F User Data] in case of magnetic field strength measurement. When the text file created beforehand is selected, the data is written. * Install the specified USB driver in the personal computer prior to using the PC software. (Refer to “25.3 Installation of Driver”) 4) Method of using original program for writing 1. Prepare the USB communication software. Connect the personal computer to the 2650A/2651 series with the included USB cable and turn on the power of the 2650A/2651 series. 2. Write the data into the unit. Transfer the data in the following format with the USB communication software. * Format In case of electric field strength measurement; EFUSER “frequency”: ”compensation data”, “frequency”: “compensation data”, · · · In case of magnetic field strength measurement; MFUSER “frequency”: ”compensation data”, “frequency”: “compensation data”, · · · Example of CP-2S * Write the unit with a capital letter as it is case sensitive. G (GHz) is also available. 3. When the writing ends correctly, “OK” is returned. 5) How to use Set the measuring function of the 2650A/2651 series to electric field strength measurement mode or magnetic field strength measurement mode. By pushing [MEAS] → [E/F ANT], electric field strength measurement mode is set. By pushing [MEAS] → [M/F PROBE], magnetic field strength measurement mode is set. Select “USER” from antennas or probes on the display by pushing [F1]. Then, the measurement by the written data will begin. * The written data remains even if power is turned off. * The measuring mode returns to a usual measurement mode when turning off power. 6) About antenna gain

In the following context, the antenna gain means an absolute gain. When the antenna gain is a relative gain, it can change into an absolute gain by adding +2.15 dB. Absolute gain [dBi] = Relative gain [dBd] + 2.15 dB As a reference, the conversion formula to electric field strength is indicated below: E = √(480π2 x Pa) / (Ga x λ2)) E: Electric field strength [V/m] Pa: Received electric power [W] Ga: Antenna gain [times] = 10(antenna gain [dBi] ÷ 10) λ : Wavelength [m] = (3 × 108) ÷ frequency [Hz] 26.
