Channel switch control/s test socket is normalized. Off isolation is measured across an off channel. On loss is

the bandwidth of an On switch. VISO, Bandwidth and VONL are independent of the input signal direction.

VISO = Off Channel Isolation = 20 Log VIN for VIN at 100 kHz

for VIN at 100 kHz to 50 MHz

Bandwidth (BW) = the frequency 3 dB below VONL

VCT = Use VISO setup and test to all other switch analog input/outputs terminated with 50 W
