  • Optimal Accuracy
  • 40 dB Dynamic Range
  • Compact & Easily Transportable
  • No On-Site Calibration Required

CAPABILITIES

Instantaneous and Simultaneous Local or Remote Monitoring of Forward Power, Reverse Power, and Load VSWR. (Figure 1,2)

Accuracy.

  • Multi-Octave Solution within ± 5% of Customer Lab Standard, Across a Full 40 dB Dynamic Range.
  • Up to 10 specific frequency points which will provide accuracy within ± 1% of Customer Lab Standard.

Calibration.

  • No On-Site Calibration Required.

  • Customer can set up a visual alarm via relay.
  • Signal can be sent to a Customer’s closed loop.

Full Temperature Monitoring/Alarm Capability. (Figure 1,2)

  • One sensor, Internal Measurement, within Meter.

PROGRAMMING AND ADMINISTRATIVE CONTROLS

Programming Capabilities.

  • Power Meter is SNMP programmable using Customer’s preferred interface. (A LabView Driver is available for LabView Users).
  • Power Meters allow for access to internal network. This will allow for external access to the Meter and for proper email notification. (Figure 3)
  • A Static IP address can be used to connect to the Internet directly or through a router.
  • Power Meters can send periodic emails by selecting from the Periodic Email pulldown menu. This includes all main screen parameters and a spreadsheet of data for record keeping purposes. (Figure 4)
  • Email notification can be set to None, Faults Only, or Warnings and Faults.

Administrative Controls.

  • Customization of a Power Meter name, as displayed remotely. Ability to enter a site name or location. (Figure 5)
  • Power may be displayed as kW, W, or dBm for both Forward and Reflected Power. (Figure 5)
  • Load VSWR Condi􀆟on may be displayed as VSWR, Return Loss, or RHO. (Figure 5)
  • Temperature may be displayed as Fahrenheit or Celsius. (Figure 5)

Remote I/O allows access to several important parameter setings.

  • Programming the function of the two on-board relay closures. (Figure 7)
  • Full Scale Indication of the Forward and Reflected D.C. sample power indications (normally factory set).
  • Configuration of up to four interlock groups. (Figure 7)

RELAY 1 can be programmed as an interlock closure or alarm closure. When set to INTERLOCK, the relay will remain closed as long as the Reflected Power is less than the programmed threshold and the conditions of the enabled interlock group(s) is satisfied.

RELAY 2 can be programmed as a second Interlock. Interlock options include an ALARM RELAY, an RF PRESENT CLOSURE, and an RF PRESENCE THRESHOLD. The RF PRESENCE THRESHOLD can be programmed to engage when RF is below a programmed threshold. This seting is a valuable tool for RF safety plans, allowing remote or local indication of RF Presence.

Figure 8

  • The Reflected Power sample can detect a threshold dependent on a high reflected power condition. The Power Meter can be programmed to open a relay upon sustained RF fault conditions.
  • The relay can be used to interface to a transmitier or power amplifier to turn it off or on for an external alarm.

General Purpose Inputs with multiple uses. (Figure 8)

  • Track Switch Closures (Assign to interlock group).
  • Trigger Alarm Relay (Sends email alert).
  • RF Presence Status/Alarm (Safety feature).
  • Alarm Activated Switch.
  • Customer can format Trigger Alarm Relays to issue Alerts via Audio/Visual Indicators, as well as, Email Warnings for Offsite and Remote Users.
