Whether for routine maintenance or new interactive network installations, CaLan products offer a range of solutions. These products cover the entire 5 MHz to 1 GHz frequency range with exceptional speed – 60 channels of visual and aural carriers in less than 2 seconds.
This portable field instrument with forward sweep and SLM capability can also receive ingress data transmitted by the 3010H.
Cost-Effective Signal-Level Measurement
The portable, rugged 2010 SLM Plus provides an affordable, entrylevel option for customers. Measurements include carrier amplitude, digital channel power, carrier-to-noise ratio, and hum. The fourchannel adjustment mode allows technicians to view four channels at a glance, for a quick, system-wide check of the lowest, highest and AGC pilot frequencies.
Digital Power Measurement
Digital signals cannot be measured with conventional methods used for video carriers because their power is spread over a band unique to each form of digital signal. CaLan products incorporate a digital signal measurement capability – technicians need only enter the center frequency, span and format for each digital signals in the unit’s channel table. The family also provides accurate average power measurement for return path TDMA (bursted) carriers.
Digital signal power is the total average power over a channel bandwidth around its center frequency. The 3010B can adapt to the unique bandwidth power characteristics of digital signals to make measurements as simple as reading a number on the display.
The 3010B can store up to 90 history files in any one of six formats: level measurements, normalized channel scan traces, sweep traces, spectrum scan traces, and ingress measurement results. Each file includes time and date stamps with a 40-character, user-defined label.
