Signal Generator Overview

Rear Panel

22. 10 MHz OUT

This female BNC connector outputs a nominal signal level of > +4 dBm and has an output impedance of 50 ohms. The accuracy is determined by the timebase used.

23. STOP SWEEP IN/OUT

This female BNC connector (Option 007 only) provides an open- collector, TTL- compatible input/output signal that is used during ramp sweep operation. It provides low- level (nominally 0 V) output during sweep retrace and band- cross intervals. It provides high- level (nominally +5 V) output during the forward portion of the sweep. Sweep stops when this input/output connector is grounded externally. When operating as an input, the nominal impedance for this connector is less than

10 ohms. When operating as an output, the nominal impedance is approximately 4.2 kohms.

24. BASEBAND GEN CLK IN

This female BNC connector accepts a sine or square wave PECL clock input with a frequency range of 200 MHz to 400 MHz, resulting in sample rates of 50 MSa/s to 100 MSa/s. The recommended input level is approximately 1 Vpeak- to- peak for a square wave and 1 dBm to 6 dBm for a sine wave. This allows baseband generators from multiple signal sources to run off the same clock.

25. Z-AXIS BLANK/MKRS

This female BNC connector (Option 007 only) supplies a +5 V (nominal) level during retrace and band- switch intervals of a step, list, or ramp sweep. During ramp sweep, this female BNC connector supplies a –5 V (nominal) level when the RF frequency is at a marker frequency and intensity marker mode is on. This signal is derived from an operational amplifier output so the load impedance should be greater than or equal to 5 kohms. This connection is most commonly used to interface with an Agilent 8757D Scalar Network Analyzer.

26. SWEEP OUT

This female BNC connector outputs a voltage proportional to the RF power or frequency sweep ranging from 0 V at the start of sweep and goes to +10 V (nominal) at the end of sweep, regardless of sweep width.

The nominal output impedance is less than 1 ohm and can drive a 2 kohm load.

When connected to an Agilent Technologies 8757D network analyzer, it generates a selectable number of equally spaced 1 ms, 10 V pulses (nominal) across a ramp (analog) sweep. The number of pulses can be set from 101 to 1601 by remote control through the 8757D.
