Frequency Extension Solution (For Agilent PNA)
Monday, 07 September 2009

Description

The FEC-01/FEC-02 Frequency Extension Controller is part of the FTL mmwave measurement extension solution.

It ensures that FTL mm-wave extender products FEV-XX are fully compatible with Agilent PNA/PNA-X and Anritsu 37XXXD/Vector Star Vector Network Analyzers and offers the best s-parameters accuracy available on the market.

Key Distinguishing Features

1. Directivity

Farran Technology heads offer a minimum directivity of 40dB (45dB typ.) from 50-110GHz and minimum of 35dB (40dB typ.) for 110-170GHz.

Directivity is a measure of how well the coupler in the heads isolates the forwward and reverse signals. It is particularly important when measuring reflection coefficients of the DUT and directly affects the accuracy of the measurement. In the case of small reflections for a well matched DUT, a coupler with lower directivity will introduce undesirable amplitude and phase errors to the measurement. The higher the directivity value the better the accuracy of the measurement of low reflection DUT's.

2. Test Port Input Power Gain Compression Point (GCP @ 1dB)

Farran Technology heads offer Gain Compression points of +10dBm (50-75GHz), +6dBm (75-110GHz) and +3dBm 110-170GHz. These figures are specified for P0.1dB rather than P1dB as it is more appropriate with the measurement error levels associated with the measurement set-up. High compression point ensures linear system operation with relatively high input signals.

3. Dynamic Range

Farran Technology offers Dynamic Ranges of >100dB (50-75GHz), >100dB (75-100GHz) and >80dB (110-170GHz). These figures are based on actual system performance (i.e. two heads, controller and VNA) with all noise sources and cross-talk effects taken into account. Our dynamic range plots are presented for worst case scenario i.e. single sweep plots with no averaging or smoothing used and an IF bandwidth of 10Hz. It is important that the dynamic range is specified for the whole system and is a measure of the maximum output power available to the minumum detectable signal in the given IF bandwidth. It defines the system ability to measure extremely low signl levels with minumum error and is particularly useful with the measurement of high rejection DUT's and material characterisation.
