The 120 DSP signal level meter is the most cost-effective and dependable tool available for all of your basic CATV installation needs. This device features a compact, rugged design, easy-to-use color user interface, and an unparalleled selection of digital and analog channel measurements.

Autotest Apps
The 120 DSP streamlines your testing procedures while making installation and troubleshooting more efficient with the use of Autotest apps. These apps allow users to perform a Return Spectrum and Channel Plan Scan of the channels included in the selected channel plan. The results are then compared to a specific set of measurement limits and displayed with familiar color-coded Pass/Fail results. All of this can easily be accomplished just by simply pressing a single button.

Job Management
With the included Job manager, technicians have the ability to enter job information that can be attached to any test results. Notes can also be added directly to each job so the technician can report any faults, anomalies or job codes related to the work being performed.

Level Measurements
When testing or troubleshooting within your analog, digital or mixed analog/digital transmission system, the 120 DSP makes the perfect tool for measuring the power levels of all of your analog and digital QAM carriers.

Additionally, for QAM carriers (including deep interleave) the 120 DSP provides Constellation, Equalizer Tap, MER and BER measurement displays. This allows users to quickly analyze 64 and 256 QAM downstream channels for quality verifications or to locate impairments with the meter, all right out of the box.

Channel Plan Scan

With its channel plan scan feature, the 120 DSP can also display the frequency response of the entire channel lineup. This measurement displays a color-coded bar graph of each channel or your favorite channels in the active channel plan. The channel plan scan also includes on-screen markers that can be adjusted to perform a tilt measurement.

Spectrum Measurements
The 120 DSP comes standard with the ability to display the the full return spectrum from 4 to 110 MHz. The spectrum display provides peak measurements, color-coded markers, and delta measurements. This feature also includes adjustable detector modes which are useful for capturing bursty transient noise. Optionally, the 120 DSP can also be equipped to perform forward spectrum measurements from 5 MHz to 1000 MHz.

Standard Testing Features:

  • Return Spectrum Analysis (4 to 110 MHz)
  • Level Measurement
  • C/N Measurement
  • QAM Measurement (MER/BER/Constellation/EQ)
  • Complete Channel Plan Scan with Tilt Measurement
  • Network Test Suite with Ping, Traceroute, & Throughput Measurements

Standard Interfaces:

  • RF Test Port (F-Type)
  • RJ45 Management Port (10/100 Mbps)
  • Mini-USB Type B Female Charge & Data Port

Simple Yet Powerful
Providing the widest range of functions for an installer available today (as standard options), the 120 DSP includes virtually all the testing options an installer or service technician needs to verify service quality and easily identify and fix problems in the field.

Why calibrate this product?

Frequencies/levels need to be within specifications to guarantee precise and reliable results.

Factory standards to ensure accuracy

Factory standards to ensure accuracy

VIAVI Calibrates to TL9000 factory standards to ensure your instrument is certified to measure accurately, as it did when it came off the factory line.  Instruments that are out of calibration will produce unreliable measurements and can create false passing or false failing test results that often cause your team repeat work.  We maintain, polish and clean all fiber connectors, fix pigtail connections that are internal to the product to ensure all ports stay in good working order and upgrade software / firmware to the latest approved release to enable enhancements. VIAVI Care Plans are the most cost-effective way to plan for calibration with a low, discounted price at the time of instrument purchase, however fixed rate calibration can be purchased at a later date on a separate purchase order.

  • Ensure accurate measurements that meet calibration and service level agreements, ISO and TL standards for network test procedures.
  • Ensure all test transmission signals work properly to avoid issues such as not reaching full line rate testing rate required to validate service bandwidth, speed and quality of service (QoS).
  • Maintain ports and connectors to keep test transmissions working properly and to extend the life of the instrument. For example, if optical connectors and, lasers are bad or electrical/RF interface ports are loose after years of connection cycles, OTDR, TDR, and Radio Frequency measurements will not work properly.
  • When doing construction, installation and activation work that must be certified, all network components typically must be tested with a certified, calibrated instrument to preserve warranty from manufacturer, such as fiber optic cable manufactures. 
  • Accurate RF frequencies and optical wavelengths are critical to meet measurement specifications.  If using these to validate network elements, power levels, transmission rates, out of specification tools will prevent validation of network elements and signals.

How will my measurements be affected if the product is out of calibration?

Out of specification measurements could cause unnecessary repeat calls customer service issues.

What are the most common implications of these issues to the business?

What are the most common implications of these issues to the business?

  • Uncalibrated tools produce unreliable measurement results that can't be certified to specifications and may violate service level agreements or ISO/TL9000 standards with your customers and their network equipment vendors.
  • QoS certification may be inaccurate and generate a repeat test need. Contractors are often not compensated or could be delisted as an approved service supplier due to incorrect results.
  • Full manufacturer  warranty (20-30 years) from cable suppliers (e.g. Corning, CommScope, Belden, ect.) will only be granted if the installation is certified with a calibrated instrument, thus the network owner is motivated to comply with correct installation certification procedures to retain and enforce the warranty on expensive cabling and optical network elements, etc.

Common Business impacts include:

  • Lost revenue, customer complaints and increased costs: 
  • Most network operators track and audit repeat work done by sub-contractors and often there is a billing dispute in these cases.  Contractors with high rates of inaccurate test results are usually hired for less or not at all when not meeting SLA agreements or quality metrics.   
  • For Network Operators, repeat service quality issues with customers often causes added cost, customer dissatisfaction and loss of business.  

Example:

Let's look at OTN/SONET/SDH/E1/T1 and various FTTX, DOCIS and xDSL measurements.  It is critical to reach full line rate (1G, 10G, 40G, 100G) to test service performance and service error rates.  If the uncalibrated tester can not reach full line rate during testing, a customer may be left with suboptimal performance that will quickly create complaints or alternatively, the technician could end up chasing phantom network problems that do not exist.
