Key Features & Specifications

  • Up to 6 dB improvement over standard typical output power levels
  • +16 dBm typical output power up to 6 GHz


Eliminate the Need for an External Amplifier

Option UNB High Output Power with Mechanical Attenuator provides up to 6 dB power improvement over the standard output power level. With 6 dB more power, the ESG is able to overcome system losses and drive high-power devices without an external amplifier, thereby simplifying and reducing the cost of test.

Note: Option 506 (250 kHz to 6 GHz frequency range) includes the Option UNB mechanical attenuator.

Typical Applications

Option UNB is recommended for signal generation applications that require high power RF test signals to stress the device under test. Typical applications include blocking and interference test, transceiver test, component test, and amplifier linearity test.

This option cannot be added as a product upgrade – only available at time of purchase.
