Signal Generator Overview

16. Digital Bus

This is a proprietary bus used for Agilent Baseband Studio products, which require an E8267C with Option

602.This connector is not operational for general purpose customer use. Signals are present only when a Baseband Studio option is installed (for details, refer to www.agilent.com/find/basebandstudio). The

Dig Bus annunciator appears on the display when the Digital Bus is active (and the internal oven reference oscillator is not cold—they appear in the same location).

17. WIDEBAND I INPUT

This female BNC connector (E8267C only) is used with wideband external I/Q inputs (Option 015). It accepts wide-band AM and allows direct high-bandwidth analog inputs to the I/Q modulator in the

3.2−20 GHz range. This input is not calibrated and accepts a 0 dBm maximum power. On signal generators without Option 015, this connector is non-functional.

18. WIDEBAND Q INPUT

This female BNC connector (E8267C only) is used with wideband external I/Q inputs (Option 015); on signal generators without Option 015, this female BNC connector is non-functional. This female BNC connector allows direct high-bandwidth analog inputs to the I/Q modulator in the 3.2 to 20 GHz frequency range. This input is not calibrated and accepts a 0 dBm maximum power.

19. COH (COHERENT CARRIER OUTPUT)

This female SMA connector (E8267C only) outputs an RF signal that is phase coherent with the signal generator carrier. The coherent carrier connector outputs RF that is not modulated with AM, pulse, or I/Q modulation, but is modulated with FM or Φ M (when FM or Φ M are on).

The output power is nominally 0 dBm. The output frequency range is from 249.99900001 MHz to 3.2 GHz; this output is not useful for output frequencies > 3.2 GHz. If the RF output frequency is below

249.99900001 MHz, the coherent carrier output signal will have the following frequency:

•Frequency of coherent carrier = (1E9 − Frequency of RF output) in Hz.

•Damage levels are 20 Vdc and 13 dBm reverse RF power.

20. I OUT

This female BNC connector (E8267C only) can be used with an internal baseband generator (Option 002/602) to output 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 in-phase component of an external I/Q modulation that has been fed into the I input connector. The nominal output impedance of the I OUT connector is 50Ω , dc-coupled.
