描述
Continuous sweep of frequency and power
The PSG equipped with Option 007 enables fully synthesized analog frequency and power sweeps. This is important when using the PSG as the stimulus for swept stimulus/response measurements, such as gain and frequency response. Fully synthesized signal generators are phase locked during the entire frequency sweep, excluding band crossings. This results in superior frequency accuracy that is typically 10 to 100 times better than traditional "lock and roll" sweepers that are phase locked at the beginning of the sweep and run open-loop for the remainder of the sweep. The PSG's high output power and increased sweep speed result in more dynamic range and increased throughput for stimulus/response measurements.


Interface with the 8757A/C/E/D scalar network analyzers
The PSG interfaces seamlessly with the Keysight 8757D scalar network analyzer for fully automated network measurements. Add another PSG to this setup for swept two-tone tests. Ten independent, continuously variable frequency markers are available on the PSG that allow accurate analysis of a device at critical frequencies. Option 007 also provides square-wave modulated RF for use with the AC detection mode available on the 8757D. AC detection reduces the effects of broadband noise, thermal drift and other unmodulated signals that can degrade measurement performance. See the 8757D Scalar Network Analyzer User's Guide for more information on the AC detection mode.

Typical applications
The ramp sweep option is recommended for stimulus/response measurements that require a fast, continuous analog ramp sweep, rather than a slower digital stepped sweep. Continuous sweeps are typically required for accurate characterization of gain, frequency response, isolation and return loss of components such as amplifiers, filters, and mixers. The PSG's wide dynamic range also increases measurement accuracy of filter rejection and switch isolation. For two-tone (master/slave) swept measurements on mixers and other devices, two PSGs can synchronously track each other with independent control of start and stop frequencies.


How to upgrade
If you currently own an E8247C PSG, it can be upgraded to include Option 007 by ordering E8247CK-007.




 
Automated scalar network analysis- The PSG is the only source with a scalar interface that enables fully automated swept stimulus/response measurements with the 8757D scalar network analyzer. Keysight 8757A/C/E scalar network analyzers can also be used with the PSG signal generators in manual mode.
More dynamic range- The PSG's high output power improves the dynamic range of stimulus/response measurements with the 8757A/C/D/E scalar network analyzer by approximately 10 dB at 20 GHz.
Swept two-tone testing- The PSG master/slave configuration, along with the 8757D, provides you the ability to measure the performance of a device under test with two input signals. Many applications require two LOs to be swept simultaneously with a constant frequency offset between the two sources.
Alternate sweep- This function provides the ability to make real-time measurements, alternating successive sweeps between the PSG's current sweep state and any of the sweep states stored in memory. The device's response may be displayed on the 8757D over two independent frequency or power ranges. When testing amplifiers in manufacturing, the alternate sweep feature can be used to compare small signal gain and large signal gain for real-time 1-dB gain compression measurements.
Superior accuracy- Exceptional frequency, power, and marker accuracy improves measurement uncertainty and yield rates.
Up to 10 markers available- Setup and generate up to 10 different markers with the PSG's convenient table-based marker editor to aid in scalar measurements with the 8757D. Frequency and amplitude data for the currently selected marker is automatically displayed on the 8757D's measurement screen, allowing you to quickly and easily identify cardinal points in your measurement.
