Description
Typical Applications
- Harmonic level measurements to 18 GHz in production test
- Intermediate Frequency Interface for 5G Research and Development
- 802.11ax (U-NII-5 5925-6425 MHz, U-NII-6 6425-6525 MHz, U-NII-7 6525-6875 MHz, U-NII-8 6875-7125 MHz) testing on legacy 6 GHz Instruments
Both up- and down-conversion functions are housed in a single-slot PXIe module. An independent local oscillator (LO) is available for each block. Optional LO input ports are provided to support measurements requiring extremely low phase noise performance.
The down-converter includes a bypass path to minimize cable swapping when the mixer is not required. The bypass path includes a user-selectable filter bank and low noise amplifier for signal conditioning purposes. For harmonic measurement applications, a bank of high pass filters (HPF) is available to reject the fundamental signal and provide better dynamic range. The down-converted signal is passed through 5GHz intermediate frequency (IF) filter for spurious rejection prior to output from the module.
Like its counterpart, the up-conversion path includes bypass capability and several signal conditioning options. Self calibration of the instrument is possible using the built-in loop back signal in the up-converter.
