SNA5000A Vector Network Analyzer User Manual 54
Application: Used to precisely calibrate any pair of ports when no calibration kits are readily
Available.
Note: Difference matching calibration may be required (Delta Match Cal)
Overall accuracy: Very high
Calibration kits required: Straight, reflection, line, or similar combination
Corrected system error:
• Directivity
• Isolation
• Frequency response
transmission tracking
• Source match
• Load match
• Frequency response reflection
tracking
SOLT:
Application: Used to accurately calibrate any number of ports
Overall accuracy: High
Required calibration kits: short circuit, open circuit, load, through) or ECAL electronic
calibration parts module
• Directivity
• Isolation
• Frequency response
transmission tracking
• Source match
• Load match
• Frequency response reflection
tracking
Enhanced Response:
Application: Calibrate two ports when only one direction (forward or reverse) is needed for
measurement. Because no secondary scanning is required, the measurement is
faster.
• The reflection calibration element (open, short circuit, or load) is connected to
the source port to be calibrated.
• The defined through-through or flush through-through calibrator kits are
connected between port pairs.
• The mechanical calibration kit is much faster than the SOLT. You can also use
ECAL.
To select an enhanced response, do the following:
Keys operation:
Press Cal, using the knob or arrow keys, to focus on the Cal→Basic Cal parameter
item. Select port1 & port2 from the interface menu, Select Enhanced Response
1→2 or Enhanced Response 2→1 in the Cal Type, Press ENTER or the knob to
select the current option.
Overall accuracy: High
