Calculated impedance measurement accuracy (continued)  
Figure 3. |Z|, |Y| Measurement accuracy when open/short/load  
calibration is performed. Oscillator level = –33 dBm. Point averaging  
factor ≥ 8 within ± 5 °C from the calibration temperature.  
Figure 4. |Z|, |Y| Measurement accuracy when open/short/load  
calibration is performed. Oscillator level = –33 dBm. Point averaging  
factor ≤ 7 within ± 5 °C from the calibration temperature.

and with low-loss capacitor calibration (Typical).  
Measurement Support Functions  
Error correction  
Available calibration and compensation  
Open/short/load calibration:  
Connect open, short, and load standards to the desired reference plane and measure  
each kind of calibration data. The reference plane is called the calibration reference  
plane.  
Low-loss capacitor calibration:  
Connect the dedicated standard (low-loss capacitor) to the calibration reference plane  
and measure the calibration data.  
Port extension compensation (fixture selection):  
When a device is connected to a terminal that is extended from the calibration  
reference plane, set the electrical length between the calibration plane and the device  
contact. Select the model number of the registered test fixtures in the E4991B’s setup  
toolbar or enter the electrical length for the user’s test fixture.
