Typical measurement accuracy when open/short/50 Ω Ω Ω Ω Ω /low-loss-capacitor calibration is done
Conditions
• Averaging on point factor is lager than 32 at which calibration is done.
• Cal Points is set to USER DEF.
• Environment temperature is within ±5 ° C of temperature at which calibration is done, and within 13 ° C
to 33 ° C. Beyond this environmental temperature condition, accuracy is twice as bad as specified.
• 7 mm connector is used.
