One of the known manufacturers of spectrum analyzers is Avcom of Virginia Inc. The company's spectrum analyzer products rangers from conveyable ones to rack mount models.
Among the conveyable model of Avcom spectrum analyzers consist of the Psa-37D model. This model is dedicated for satellite and Catv industries and is can cover the 1 Mhz - 4.2 Ghz frequency range.
Rotary Encoder
Among its other features consist of precision rotary encoder tuning, independent span and resolution Bw and readout Ku Band offsets. Meanwhile the conveyable Psa-39B is used for satellite and satellite Hdtv. This model is dedicated on the L band 950-2150 Mhz and displays L, C, Ku frequencies only. The unit has less than -90 dBm sensitivity and is adequate with 5 resolution B/W's that range from 3 Mhz to 75 Khz.
Avcom's rack mount spectrum analyzers vary from satellite vehicles and uplinks to remote spectrum monitors and offsite satellite communications. For the latter one, Avcom offers the Rsa-45fDe model. This one has 950-2150 Mhz L-Band dual satellite capabilities and has resolution bandwidth screen memories. With the right Avcom Ncsa software, you can remote monitor the measurements straight through your own computer. Other rack mounted analyzers consist of the Msa-4570D and the Msa-45D models. Both models incorporate a 950-2150 Mhz spectrum analyzer, use dual resolution bandwidth and have 50 user memory screens each. The only contrast is the Msa-45D's 50-200 Mhz spectrum monitor. Both models are appropriate in width and have the 19" rack mount.
For Catv analysis, the Psa-37Xp with its independent span and resolution bandwidth can be enough. The Psa-37Xp is able to cover the whole Catv frequency range easy with its 1 to 1100 Mhz coverage. Moreover, the model is adequate with the satellite L band from 950 to 2150 Mhz which has a direct range of up to 4.2 Ghz. The Psa-37Xp is great for testing and setting head-end levels because of the capabilities of the unit to accomplish as much as ± 2 dB amplitude accuracy. Also, this Avcom unit is adequate with a built-in Li-Ion battery pack. With the built in charger, you can fee the unit and work right at the antenna site. You have freedom of movement since you no longer need an prolongation cord because of the internal power supply.
There are also two more spectrum analyzers that you surely want to look at. These are the Avcom Psa-65C has an added light weight backup ideas which ensures continued usage. The other one is the Avcom Psr-3000 video guard receiver which is primarily used to uncover private microwave video transmitters.
