Optional modules for ultra-high frequency lock-in amplifier:

UHF-DIG digital converter
The integration of lock-in amplifiers and digital converters is committed to expanding the applicability of this revolutionary instrument

UHF-MF multi frequency option
This multi frequency option gives HF2LI extraordinary flexibility in the selection of input channels, oscillator frequencies, and various demodulator coefficients, and supports simultaneous demodulation of 8 arbitrary frequencies.

UHF-MOD AM/FM modulation option
UHF-MOD is one of the options of UHFLI, which supports direct analysis of the sidebands of dynamic amplitude modulation (AM) and frequency modulation (FM) circuits. This option can help users accurately determine the periodic changes in the frequency or amplitude of application signals.

UHF-PID/PLL controller
The PID options include four configurable PID controllers to control various parameters and units. Perfectly integrated into lock-in amplifiers, programmable PID can operate a wide range of applications. Especially PID can be used as a part of both. Customers can easily find the circuit filtering parameters.

UHF-BOX equalizer
A fully digital integrated averager that opens up new perspectives and innovative ways of working. The functions and settings of old-fashioned instruments can be creatively digitally implemented.

UHF-RUB rubidium atomic clock
The rubidium atomic clock has a highly accurate clock generator that has extremely high precision and low drift in accurately measuring the permissible frequency for hours, days, and years.

UHF-10G Optical Ethernet
The UHF-10GbE Ethernet interface provides a high-throughput communication link between UHF instruments and upper computers. In point-to-point topology operation, the target application tends to prefer digital sampling transmission instead of intermediate analog conversion.
