FT-991 – MAIN V02.02 – DSP V01.04 – TFT V02.01 JUL.24 – VA7OJ’ RX & TX All Tests

FT-991  HF, 50, 144, 430 MHz All Mode – Yaesu USA Update the Firmware MAIN Ver. 02.02  – DSP Ver. 01.04 and TFT Ver. 02.01 of 24/07/2015 – VA7OJ’ FT-991 Complete Tests Report – See …news and link below –

FT-991-Adam-02

The complete FT-991 test report is now available on the website by VA7OJ’ Adam – (Receiver Tests & Trasmitter Tests) rx: MDS – RMRD – DR3 – DR2 – FM IMD rejection – NPR – Image & 1st IF rejection – AGC impulse response – DNR SINAD // tx: Power Output -CW keing envelope and sidebands – ALC compression test – Trasmitted 2 tone IMD – Tramitted Composite noise HF 50 144 & 430 MHz (22 pag.)  (Grazie, Adam per questo eccellente Test report!)

Link to: Download the Complete Tests rx-tx  of 25/7/2015

Receiver performance evaluation using notched noise, tune DUT (FT-991) such that the IF passband is centred in the notch. Calculate NPR using Equation: NPR = Ptot – BWR – MDS. – All the NPR measurements, by VA7OJ, Adam are performed in SSB mode, at 2.4 kHz bandwidth. The bottom of the notch in the noise generator (a Wandel & Goltermann RS-50 White Noise Generator ) bandstop filter is 3 kHz wide. Adam uses the 3 kHz roofing filter in the DUT (automatically selected in SSB mode in the FT-991 Transceiver)

Link to: Download the FT-991 RX NPR Test of 18/7/2015

A typical NPR test case emulates 1200 contiguous SSB signals, each at S9 + 30 dB. The higher the NPR figure obtained in the test, the better the DUT will be able to survive such extreme conditions. – The NPR test is also useful for identifying IMD choke points in a receiver front end, e.g. in RF steering diodes, and also passive IMD (PIM) in crystal filters, inductor cores and even some capacitor dielectrics.
I would categorise NPR ranges as follows: Measurement limit: ~ 95 dB (notch depth) / 85 dB and up: Excellent / 80-85 dB: Very good to excellent  /  75-80 dB: Very good / 70-75 dB: Good / 65-70 dB: Acceptable to good (source by Adam, VA7OJ – grazie!)

1) V/D mode = communicates Voice & Data simultaneously and using 6.25 + 6.25 kHz bandwidth – [DN] is displayed on the LCD – the station location info is contained within the tx digital signal;
2) Voice FR mode (Full Rate) = trasmits digital voice using the full 12.5 kHz bandwidth – [VW] is displayed on the LCD – the location info is not included in the tx signals;
[Note] Data FR mode (Full Rate) = high speed data communication mode is not supported in the FT-991!  (Data Full Rate by C4FM is not possible).
