NOTE
f : frequency [MHz].
These characteristics apply when an OPEN is connected to each port.
Test signal level should be £ 0.5 Vrms when the measured impedance is £ 50 W.
Beyond a temperature of 23 ± 5×C, the test signal level setting accuracy decreases to half
the value described.
Current Signal Level
NOTE f : frequency [MHz].
These characteristics apply when a SHORT is connected to each port.
Test signal level should be £ 20 mArms when the measured impedance is £ 50 W.
