Atec Agilent-8591C User Manual

A complete test solution for your cable TV system
The Agilent Technologies CaLan 8591C is the industry’s only one-box tester for all RF and video measurements. With this analyzer you can make RF and video measurements without interrupting your cable TV system. The CaLan 8591C is a f lexi­ble troubleshooting tool and an automatic system tester. Non-interfering measurements are performed at the push of a button and can be made automati­cally.
The flexible hardware and software design lets you easily upgrade the analyzer to accommodate changes in required measurements and measurement tech­niques. For added flexibility, NTSC format is stan­dard, with options available for worldwide PAL and SECAM formats and frequency plans.
CaLan’s cable TV analyzer provides all this per­formance in a rugged, portable instrument ideal for field use. It comes in a durable carrying case that makes it easy to transport and that protects it from moisture and dirt. And the analyzer is fully operational within the case, so you never need to remove it.
Agilent CaLan 8591C cable TV analyzer
All specifications apply over 0°C to +50°C. The analyzer will meet its specifications after 2 hours of storage at constant temperature within the oper­ating temperature range, 30 minutes after the ana­lyzer is turned on and after CAL FREQ, CAL AMPTD have been run. Character-istics provide useful, but non-warranted, information about nominal per­formance.

Cable TV RF and video measurement
These specifications describe warranted performance of the Agilent CaLan 8591C cable TV analyzer and the CaLan 85721A cable TV measurement personality from 0° to 50°C after the warmup and calibration described earlier. Characteristics provide useful, but non-warranted, information about nominal performance. NTSC-formatted signals only are covered. A RAM card is needed for the 85721A to store test results. Test data may also be printed using an HP InkJet or HP LaserJet printer.

C/N, CSO, and CTB measurements
The four graphs summarize the combined CaLan 8591C and 85721A characteristics for C/N, CSO, and CTB testing on cable TV systems for CSO and CTB measurements with up to 77 channels and no amplitude tilt, and for C/N measurements with single channels. C/N, CSO, and CTB measurement accuracies and ranges can be read from the relevant graphs. They depend on the visual carrier peak level, the measurement reading, and the total power input to the analyzer. For C/N measurements with a preselector, there is no optimum range and the accuracy bound­aries drop by the preselector’s insertion loss (typically 2 dB).
