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.

产品类型 | 推荐计划 | BronzeCare![]() | SilverCare![]() | MaxCare![]() | 为什么要校准? |
---|---|---|---|---|---|
180 DSP 仪表 | Silver-5 | 为什么要校准这个产品?频率/电平需要在规范范围内,以保证准确可靠的结果。 Factory standards to ensure accuracy确保准确性的工厂标准VIAVI 根据 TL9000 工厂标准进行校准,以确保您的仪器经过认证,可以准确测量,就像它出厂时一样。未校准的仪器将产生不可靠的测量结果,并可能产生错误的通过或错误的不通过测试结果,这通常会导致您的团队重复工作。我们维护、抛光和清洁所有光纤连接器,修复产品内部的尾纤连接,以确保所有端口保持良好工作状态,并将软件/固件升级到最新批准版本以实现增强功能。VIAVI Care 计划是在购买仪器时以较低的折扣价规划校准的最具成本效益的方式,但是也可以随后以单独的采购订单购买固定费率校准。
如果产品不在校准范围内,我的测量结果会受到怎样的影响?超出规格的测量可能会导致不必要的重复呼叫客户服务问题。 What are the most common implications of these issues to the business?这些问题对企业最常见的影响是什么?
常见的业务影响包括:
示例: 让我们看看 OTN/SONET/SDH/E1/T1 和各种 FTTX、DOCIS 和 xDSL 测量。达到全线速率(1G、10G、40G、100G)对测试服务性能和服务错误率至关重要。如果未校准的测试仪在测试过程中无法达到全线速率,客户可能会得到性能不佳的结果,这将很快引起投诉,或者,技术人员最终可能会寻找不存在的虚假网络问题。 | |||
