2. Specifications 

2.1 Environmental Requirements 

 

The  electrical  performance  of  vector  network  analyzers  and  test  port  cables  are  sensitive  to 
ambient temperature drift. Most manufacturers limit the allowable temperature drift to ± 1 K during 
measurement calibration and during measurements when the network analyser error correction is 
turned on. For further information please refer to the VNA specifications. 
 

NOTE:  With your fingers being a heat source, avoid unnecessarily handling the devices 

during calibration. 

 
The calibration standards are less sensitive to temperature changes. The operating temperature 
range for which the specifications are valid is defined in the specific data sheets. 
 
 

2.2 Electrical and mechanical Specifications 

 
Electrical and mechanical specifications are defined for all calibration standards and the torque 
wrench in the specific data sheets.  

 

3. Standard Definitions 

3.1 Standard Definitions 

 
Standard  definitions  provide  the  data  needed  to  mathematically  describe  the  electrical 
characteristics of each calibration standard. Two types of standard definitions are available: 

 

Model  based

  (standard  delivery):  These  are  the  traditional  standard  definitions  and  can  be 

used  on  both  old  and  modern  VNAs.  The  values  of  these  constants  are  theoretically  derived 
from  the  physical  dimensions  and  material  of  each  calibration  standard,  or  from  actual 
measured  response.  All  necessary  values  are  printed  on  the  Standard  Definition  Cards  and 
stored as data files on an USB stick. Both are included with this calibration kit.  

 

Data based

 (optional): These standard definitions allow more accurate measurements but can 

only be used on modern VNAs. They consist of a set of complex measurement values for each 
calibration standard in a narrow frequency step size. A file containing these values for all Open, 
Short and Load calibration standards is delivered on an USB stick. 

 
These  standard  definitions  are  used  in  the  calibration  of  the  VNA  to  determine  the  systematic 
errors  of  the  measurement  system.  Please  always  use  the  most  recent  source  of  information 
(Standard Definitions Cards or VNA specific files).
