Input Connections
Test connections to the instrument are best accomplished by using the 
dual banana plug with copper wire short between the two terminals for 
low- thermal offset measurement. 
Shielded, twisted- pair Teflon interconnecting cables of minimum length 
are recommended between the calibrator and the U3606A. Cable shields 
should be earth ground referenced. 
This configuration is recommended for optimal noises and settling time 
performance during calibration.
