Maximum voltage between any conductor and ground is 42V.
To prevent damage to the S46/S46T/S46L, do not exceed the maximum
signal level specifications of the switch.
Maximum voltage: 30 V DC, 42 V peak
Maximum Power (per RF channel):
• 35 W CW at 18 GHz, 1 W switching; load VSWR of 1.20:1 maximum
• 10 W CW at 26.5 GHz, 1 W switching; load V SWR of 1.20:1 maximum
• 3 W CW at 40 GHz, 1W switching; load V SWR of 1.20:1 maximum
Termination power: 1 W per termination, 3 W total power per relay
Do not close more than one RF path per multiport switch. Degradation of
RF performance will result and the switch may be damaged.
The term GPIB (general purpose interface bus) is used in this manual. GPIB is
simply another term for the IEEE-488 bus.
