Individual Transfer Curves of Moving Magnet Cartridge Subassemblies

A Moving Magnet (MM) phono cartridge can be characterized by its overall transfer function. But the transfer function of the part that generates the signal through magnetic induction has its own transfer function, which can also be measured. By translating the latter into an equivalent electronic circuit, further insight and possibilities for optimization can be obtained. This article explains.

Red Pitaya, the company from Ljubljana, Slovenia, that pioneered the move to low cost, open-source, reconfigurable test & measurement instrumentation with its credit-card-sized STEMlab platform, launched a VNA new bridge module and application that enables STEMLab to function as an affordable vector network analyzer (VNA), a precision measuring tool that tests the electrical performance of high frequency components in the radio frequency.

British company Pico Technology has applied its expertise in compact USB instrumentation, combined with its experience with high-performance sampling oscilloscopes and time domain reflectometry, to create a new high-quality, low-cost vector network analyzer. The PicoVNA 106 is an all-new, USB-controlled, professional and laboratory-grade 300 kHz to 6 GHz vector network analyzer of unprecedented performance, portability and affordability.
