04 | Keysight | E4990A Impedance Analyzer 20 Hz to 10/20/30/50/120 MHz - Data Sheet
Voltage Signal Level
Range
5 mVrms to 1 Vrms
1 mV
Resolution
Accuracy
at four-terminal pair port of the
E4990A or 7-mm port of the 42942A
± [(10 + 0.05 × f )% + 1 mV]
± [(15 + 0.1 × f )% + 1 mV]
at measurement port of the 42941A,
16048G/H
NOTE
f : frequency [MHz].
These characteristics apply when OPEN is connected to each port.
Test signal level should be ≤ 0.5 Vrms when the measured impedance is ≤ 50 Ω.
Beyond 23 ± 5 °C of temperature, test signal level setting accuracy is twice as bad as described.

Range
200 µArms to 20 mArms
Resolution

NOTE
f : frequency [MHz].
These characteristics apply when SHORT is connected to each port.
Test signal level should be ≤ 20 mArms when the measured impedance is ≤ 50 Ω.
