How to extend the LILCO
®
Series Performance
To extend the specifications of output sensitivity, lower bandwidth (LF, 3 dB BW) and droop from
the Specifications can be achieved by changing the BNC output termination.
Tip! Selecting the right termination provides the ability to optimize the performance to best
adapt to a variety of applications.
The overall I·t capability of the transformer increases when using 50Ω, or the attenuator
ATT10BNCS.
● 1 MΩ output termination (see Specification Table)
● 50Ω termination
Reduces the output sensitivity by a factor of 2 while improving the low frequency performance
by a factor of 2.
Example: Model 13G1000 with 13 cm inner whole diameter
• Output Sensitivity: 1 V/A
• Droop: 880 %/ms (0.88 %/µs)
• Bandwidth LF: 1400 Hz
• Output Sensitivity: 0.5 V/A
• Droop: 440 %/ms (0.44 %/µs)
• Bandwidth LF: 700 Hz
● Attenuator ATT10BNCS and 1 MΩ input termination of the measuring instrument
Reduces the output sensitivity by a factor of 10 while improving the low frequency performance
by a factor of 10.
• Output Sensitivity: 0.1 V/A
• Droop: 88 %/ms (0.088 %/µs)
• Bandwidth LF: 140 Hz

Note, the attenuator ATT10BNCS requires a measuring instrument with 1 MΩ input termination.
The measurement device input termination is equal to the LILCO
