Data Sheet
Scalar and Spectrum Analysis
Combining the Agilent 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 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 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.
