Ingress Measurements The CaLan 3010H features unique ingress measurements for ongoing monitoring of burst noise, integrated average noise power in the presence of active TDMA carriers, and spectrum scan. Return Path Alignment and Ingress Detection The CaLan 3010H headend unit monitors communication with field units. When ingress interrupts communication the 3010H instantly detects the problem and transmit a "picture" of the ingress via the forward data pilot that can be viewed on any field unit. Sweep Measurements CaLan products reduce sweep update time for a typical 750 MHz system to 650 milliseconds. Slope offset control of sweep references allows sweeping of trunk and bridger amplifiers and line extenders from a single reference, automatically eliminating the need for true-tilt networks and providing time savings on each field operation. Digital Power Measurements CaLan products incorporate a digital signal measurement capability. Adapting to the unique bandwidth power characteristics of QAM, QPR, QPSK, and VSB digital formats to make measurements as simple as reading a number on the display. Return Sweep The CaLan 3010H and 3010R incorporate DigiSweep technology, the industry's fastest, high resolution, digital services-compatible sweep. DigiSweep's five-microsecond sweep pulses allow placement clase to digital signals without interference and is compatible with cable modems, telephony, interactive TV, digital music services and Internet communications.
