Meters

In the field of Cable TV, Broadcast TV, Satellite TV and the distribution of these signals there are several different types of meters used to measure the signal strength and or quality.

In the early days of television the signal strength was measured with a volt meter measuring Milivolts then converted to dBmV. This led to the development of the Field Strength meter which showed the signal level in dBmV. Early meters were call field strength meters because the measured the electric field from a transmitter. As is common in the industry the term FSM was quickly adopted for Field Strength Meter. This is the same with SLM which stands for Signal Level Meter. Both acronyms refer to the same device for testing a signal strength of a TV channel.

In today’s world of digital technology and digital TV the basic Signal Level Meter has transformed into a more complex measuring device. These meters are often capable of tuning and measuring different types of broadcast signals such as analog NTSC channels, Digital ATSC channels with both 8VSB and QAM modulation and even QPSK satellite delivered channels. In addition to signal level, today’s meters can often measure C/N or Carrier to Noise ratio, MER or Modulation Error Ratio, BER or Bit Error Ratio as well as display the constellation scheme of the modulated signal to identify signal quality issues

In addition to Meters, analyzers are used to look at and measure the entire bandwidth to evaluate signals and identify problems. Analyzers are typically more complex and more expensive than meters.

Here you will find may different levels of meters from a basic signal level only to a digital analyzer that works with a laptop to test many different digital signals. Please feel free to contact us to assist you with making the decision on which one is best for you.
