Scalar and Spectrum Analysis
Combining the Agilent / HP 85640A tracking generator with a portable spectrum analyzer results in a system having both scalar-analysis and spectrum-analysis capabilities. Use the scalar-analysis capability to perform measurements such as gain, frequency response, compression flatness, and return loss on components and sub-systems. Use the spectrum analysis capability to measure harmonic and inter-modulation distortion, as well as spurious products.
Versatility in the Field
The combination of the Agilent / HP 85640A and a portable analyzer allows you to make a wide variety of scalar measurements in the field. Check sub-system performance and make antenna return-loss measurements to isolate potential problems. Use your portable scalar system and the analyzer’s built-in FFT capability to locate faults in cables and interconnections. Opens and shorts, as well as damaged or poorly-connected cables, can be isolated and then repaired.
Portable and Rugged
Lightweight, portable, and MIL-rugged, the 85640A is the perfect addition to your 8560A, 8561A/B or 8562A/B portable spectrum analyzer. The HP / Agilent 85640A also shares the five-minute warm-up and tough environmental specifications found in these analyzers. So, it’s an ideal solution for field-service, bench, and manufacturing scalar measurements.
High Throughput and Wide Dynamic Range
A tracking generator combined with a spectrum analyzer allows measurements to be made with fast, continuous sweeps. The 85640A features a dynamic range higher than 115 dB and shares the synthesized frequency accuracy of the spectrum analyzer. This lets you quickly and accurately make real-time adjustments of devices and measure parameters such as filter rejection and switch insolation. In addition, the 85640A includes a manually-controlled, built-in output attenuator and vernier, so you can vary the output level for measurements like gain compression.
Specifications
Specifications describe the instrument’s warranted performance. Typical performance is non-warranted. Supplemental characteristics are denoted by “nominal” or “approximately”; these constitute non-warranted functional performance information derived during the design process and are not tested on a continuing basis. Unless noted, all specifications describe the instrument’s warranted performance under the following conditions: 5-minute warm-up from ambient conditions, tracking adjusted, 1-year calibration cycle, and environmental requirements met.
