21. I-bar OUT

This female BNC connector (E8267C only) can be used with an internal baseband generator (Option 002/602) to output the complement of the analog, in-phase component of I/Q modulation; on signal generators without Option 002/602, this female BNC connector can be used to output the complement of the in-phase component of an external I/Q modulation that has been fed into the I input connector.

I-bar OUT is used in conjunction with I OUT to provide a balanced baseband stimulus. Balanced signals are signals present in two separate conductors that are symmetrical relative to ground and are opposite in polarity (180 degrees out of phase). The nominal output impedance of the I-bar OUT connector is 50Ω , dc-coupled.

22. Q OUT

This female BNC connector (E8267C only) can be used with an internal baseband generator (Option 002/602) to output the analog, quadrature-phase component of I/Q modulation; on signal generators without Option 002/602, this female BNC connector can be used to output the quadrature-phase component of an external I/Q modulation that has been fed into the Q input connector. The nominal output impedance of the Q OUT connector is 50Ω , dc-coupled.

23. Q-bar OUT

This female BNC connector (E8267C only) can be used with an internal baseband generator (Option 002/602) to output the complement of the analog, quadrature-phase component of I/Q modulation; on signal generators without Option 002/602, this female BNC connector can be used to output the complement of the quadrature-phase component of an external I/Q modulation that has been fed into the Q input connector. Q-bar OUT is used in conjunction with Q OUT to provide a balanced baseband stimulus. Balanced signals are signals present in two separate conductors that are symmetrical relative to ground and are opposite in polarity (180 degrees out of phase). The nominal output impedance of the Q-bar OUT connector is 50Ω , dc-coupled.

24. BASEBAND GEN REF IN

This female BNC connector (E8267C only) is used with an internal baseband generator (Option 002/602); on signal generators without Option 002/602, this female BNC connector is non-functional. This connector accepts a 0 to +20 dBm sine wave or TTL square wave signal from an external timebase reference. This external timebase reference clock is used by the internal baseband generator for both component and receiver test applications (only the internal baseband generator can be locked to this external reference; the RF frequency remains locked to the 10 MHz reference).

This connector accepts rates from 250 kHz through 100 MHz; the nominal input impedance is 50Ω . at

13 MHz, ac-coupled. The internal clock for the arbitrary waveform generator is locked to this signal when external reference is selected in the ARB setup. The minimum pulse width must be > 10 ns. The damage levels are > +8V and < −8V.
