TA430 (insertable M-F) and TA431 (non-insertable F-F) – pictured in foreground – present a high and varying impedance mismatch, delivering the most demanding test of system measurement accuracy currently available, according to Pico.
The intention is to give confidence in an instrument, its test leads and its ongoing calibration validity – that the test leads and connectors have not become damaged, nor has environmental change degraded accuracy.
