Operation What You’ll Learn in this Chapter What You’ll Learn in this Chapter This chapter introduces you to basic preselected external-mixing functions available using an 11974 Series Preselected Millimeter Mixer. After a brief discussion of operating precautions and hints, operation procedures using the most commonly-used “host” spectrum analyzers are described.
Operation What You’ll Learn in this Chapter Operation for Each Spectrum Analyzer Band Selection describes how to select the desired millimeter band for operation. Amplitude Calibration allows you to enter in conversion-loss values for your specific operating frequency. Each 11974 band is individually characterized and labeled at the factory with a calibration chart of its conversion loss versus frequency. Preselector Peaking or Centering quickly maximizes the amplitude accuracy of a signal of interest.
Operation 11974Q Front-Panel Features 11974Q Front-Panel Features Operation Figure 3-1. 11974Q Front Panel The front panel of an 11974 Series mixer consists of an RF input port flange and two flange clamps.

Operation Operating Precautions Operating Precautions CAUTION To avoid damaging your 11974 and to assure accurate measurements, be sure to follow the recommendations in this section. Maximum RF Input Level The maximum RF input level, as stated in Table 1-2 on page 19, is +25 dBm CW, Peak, or Average. However, since the 1 dB compression point at the RF input is between 0 and +6 dBm depending on the band, meaningful measurements will end long before the damage level is reached.
Operation Operating Hints Operating Hints The following operating hints are provided for your convenience. Preventing Erroneous Preselector Peaking or Centering During Spur Searches When performing spurious response tests on a device under test (DUT), the spectrum to be measured typically contains both large and small signals. If the spurs are smaller than −60 to −65 dBc, they may be confused with the image or multiple response of the large signal.
Operation Operating Hints Remote Location of an 11974 In cases where the device-under-test (DUT) is farther away than the 1 meter LO and IF cables can accommodate, place the 11974 close to the DUT, but place the host spectrum analyzer the desired distance away. In order to preserve the excellent amplitude accuracy of the 11974, the +14.5 to 16 dBm LO power must be supplied even though the LO cables may become quite long. To supply the LO power, insert an 11975A Amplifier at the 11974 location.
Operation Operating Hints Operation Figure 3-4.
Operation Operating Hints RF Port Voltage Standing Wave Ratio (VSWR) Effects As with most bandpass filters, the magnetically tunable Barrium-Ferrite bandpass filter of the 11974 is reflective out of its passband. In addition, the 11974 does not have a programmable RF port attenuator to improve the VSWR in band or out of band. This may cause measurement errors when testing VSWR sensitive DUTs outside of their operating frequency range.
