Page 13: Overview
Overview Description The Keysight 537A coaxial frequency meter is used for measuring frequency in the 0.96 to 12.4 GHz range. Accuracy is obtained from the spiral scale. The meter contains a coaxial line coupled to a quarter- wavelength coaxial resonant cavity loaded with capacitance at the bottom of the band. -
Page 14: Measurement
The detector-indicator combination can be a thermistor mount and power meter such as the Keysight 478A and 432A, or a crystal detector and SWR meter. If a SWR meter is used as the indicator, the signal source must be modulated at 1000 Hz (sine or square wave modulation). For visual display, an oscilloscope can be used as the indicator. -

P, T Sensitivity: <–7 dBm [a] P= performance tests, T = troubleshooting. Maintenance For dial-stop gear replacement, instrument recalibration, or any other repair needs, contact your local Keysight Technologies Sales and Service office for instructions and assistance.

2, two detectors are connected together with a modulator, swept amplitude analyzer, and a dual directional coupler in a reflectometer test setup. The reflectometer is calibrated using a short. The 537A coaxial frequency meter under test is connected and the return measured. -
Page 17: Procedure
13 Disconnect the short from the reflectometer test port. 14 Connect the 537A under test to the reflectometer test port by disconnecting the short and inserting the properly terminated 537A under test. - Page 18 20.8 dB 27.8 dB 24.6 dB 21.9 dB 9.5 dB 11.0 dB 10.5 dB 9,8 dB 18 If the above limits are not met, test the 537A using a slotted line at the frequency in question.

Page 19: Overall Accuracy
A sweep oscillator, 537A under test, detector, and oscilloscope are connected in series. The sweep oscillator is set to AF to sweep the band in question. The 537A is set to the frequency in question and the notch located on the trace. The sweep oscillator is set to CW and adjusted to the center of the absorption notch of the 537A. -
Page 20: Procedure
2 Set oscilloscope for a vertical sensitivity of about 02 V/cm (ac) and horizontal sensitivity of about 1 V/cm. 3 Set sweep oscillator for ^F automatic sweep of about 3.8 GHz + 12 MHz for 537A. 4 Set the 537A to 3.8 GHz. -
Page 21: Calibration Procedure
Figure 2 Figure 3 list procedures for checking instrument specifications. If dial accuracy is not within listed specifications, adjust 537A as detailed in the Calibration Alignment Procedure, as follows. 1 Remove knob (1). 2 Remove base (11) retaining screws. With base retaining screws removed, place the 537A in upright position and make electrical hookup for OVERALL ACCURACY TEST. - Page 22 Calibration Procedure THIS PAGE HAS BEEN INTENTIONALLY LEFT BLANK.
