Abstract

The utilization of frequency ranges of up to 3 GHz (5...65 MHz for return channel, 47...860 MHz for CTV transmission, 950...2150 MHz for satellite IF, 2500...2700 MHz for MMDS) in cable TV necessitated the design of a device allowing for the levels of spectral components in the given ranges to be measured. The LFM 300 measures the AFC and PFC of passive and active devices in the 5...1000 MHz range, as well as amplifier intermodulation distortion (IMA 3 according to DIN 45004) across the top range of the TV channels transmitted over cable. The report presents technical solutions behind the design of the device.

一种多功能CTV测量装置
利用的频率范围高达3ghz(5…65返回信道，47…860兆赫CTV传输的兆赫，950…2150卫星中频，2500…2700有线电视中的MHz (MMDS)需要设计一种允许在给定范围内测量频谱分量水平的设备。LFM 300测量5…1000的无源和有源器件的AFC和PFCMHz范围，以及放大器互调失真(根据DIN 45004的IMA 3)在通过电缆传输的电视频道的最高范围内。该报告介绍了该设备设计背后的技术解决方案。
