The National Instruments SCXI-1192 is an 18 GHz, 50 Ω SCXI relay module with eight single-pole double-throw (SPDT) relays.
Core content remains expanded and crawlable.
The SCXI-1192 provides eight SPDT relays within the National Instruments SCXI platform. Its 18 GHz bandwidth and 50 Ω characteristic impedance distinguish its high-bandwidth switching function.
Power handling requires attention to both signal frequency and the number of active relays. NI's manual correction specifies that the total input power across all relays must remain within the stated frequency-dependent limits; individual relay allowances decrease when multiple relays carry power.
Only supported values belong in the table and schema.

It provides eight single-pole double-throw (SPDT) relays with an 18 GHz bandwidth and 50 Ω characteristic impedance.
No. NI's scanning-capability reference lists the SCXI-1192 among switches that do not support scanning.
No. NI's manual correction states that the total input power across all relays must not exceed the frequency-dependent limits. Use its active-relay table to determine the carry-power allowance per relay. These limits apply to carrying power without switching.
