Analog and Digital Field Strength Meter

The PROLINK-1C has frequency coverage for terrestrial TV, CATV, and microwave distribution (MMDS). It is ideal for either analog and digital measurements. The PROLINK-1C offers excellent features and technical specifications.

Signal Level Measurement

The signal level reading can be displayed numeric or a bar graph display. The numeric display is essential for definitive measurements, such as at distribution taps or amplifier points. The bar graph display is ideal for FM, UHF and MMDS antenna alignment work. The large alphanumeric LCD display is back lit, for use in low level lighting conditions. The LCD display is fast acting and the meter has good signal sensitivity. The measurement units can be chosen before delivery, or by the user with the RM-101 software. The attenuation is semiautomatic featuring a 30 dB scale range.

Audio/Video Ratio and Audio Demodulation

The Video/Audio ratio function shows the difference between the video and audio carriers. The audio carrier can be selected for different television standards. The PROLINK-1C also demodulates FM and AM radio signals, and includes a high quality loudspeaker.

Computer Interface

The user can also control the different functions of the PROLINK-1C via the RS-232C port on the meter with the optional RM-101 software. It is also possible to edit channel plans, measurement parameters, and perform other functions from the computer.

Automatic Measurements

Reports can be printed for one channel or any number of pre-selected channels. With just one instruction, the PROLINK-1C allows the user to obtain printed results of all channels. Valuable system documentation can be developed quickly and easily.

Printer Connection

Printed documentation can be obtained on any RS-232C compatible printer. If the instrument is set to the Numerical Mode, the printed list will show numerical values. In the Graphic Bar Mode, the report will show bar graphs for the video and audio levels of selected channels. This function can be very useful for documenting system-wide equalization or tilt. The instrument can also output a spectrum views of entire CATV, VHF, FM or UHF bands.

Configuration Storage

To simplify the operation of the instrument, it is possible to store measurement configurations. At power up, the preferred configuration is chosen from memory - making the meter very easy to use. In the most simple setup, the user selects the channel and then reads the level directly from the back lit LCD.

Supply To Auxiliary Devices

The option -16 adds a supply voltage to antenna amplifiers and external units in MMDS, CATV and SMATV applications.

Frequency Range Extension Option

This instrument covers the entire 46 to 870 MHz frequency band. The option OP-101-67 provides a frequency extension of 5 to 48 MHz - invaluable for 'return path' CATV/MATV measurements.

Channels or Frequencies

The use of frequency synthesis guarantees stability and assures high measurement accuracy. The PROLINK-1C takes advantage of new technology while maintaining links with established measurement practices. For instance, channels and frequencies continue to be selected by means of rotary encoder with two speeds, so that access to the required channel is quick and simple. The instrument allows the user to select any channel plan by means of the software.
