Les performances de nos récepteurs en chiffres

 

La nature humaine est ainsi faite que nous investissons beaucoup de nous même dans le choix de notre transceiver. Il est à notre image, nous nous identifions à lui et par la force des choses, on le pense parfait... Heureusement derrière les belles façades bigarrées la technique domine et les surprises sont de taille !
Bonne lecture et n'achetez pas n'importe quoi.

Mesure de l'IP3 bande 40 mètres

D'après G3SJX Radcom - RSBG

Le point d'interception n'est plus mesuré à un écart entre F1-F2 constant de 20 kHz mais à trois différents (20, 10 et 3 kHz).
La mesure a été effectuée sur la bande 40 mètres.

Notes on Receiver Table Legend

One (1) dB blocking (gain compression) test done at 100 kHz to eliminate phase noise interaction.
N.A. = Data not available.
# = Measured with SSB filter.
* = Built-in preamp actuated.
F.L = Filter limited, no measurement was possible due to signal leakage around filter.
t = Readings would have been lower if 2-kHz spacing had been possible.
^ = Measurement was phase-noise limited rather than intermodulation limited.

N.L. = Noise Limited
dBpep = dB below PEP output power.

Notes:
  1) When receiver values were given for preamp on/off, the preamp on numbers were used here. (or IPO/AIP off)

  2) When values for more than one HF Amateur band are given, the worst numbers were used.  (example:  general coverage receiver numbers
for 1.0 MHz were not considered, if a rig covers 50MHz, those numbers were not considered.)

  3) Dynamic Range and 3rd order intercept numbers for the TS-450S and TS-690S do not indicate performance as bad as such numbers would
usually warrant.  Although 3rd order products appeared at the MDS level at a fairly low level, they did not increase in amplitude with
rising input signal level as rapidly as one would normally expect. See the QST review for more details.

MDS = Minimum Discernible Signal (3db increase above noise floor). Larger negative numbers are generally better, 
but too much sensitivity can reduce strong signal dynamic range and Ip3. Pre-Amp On MDS numbers of -130 dBm 
or more are more than adequate for most HF band operating, since band noise is typically above this number. 
(Lower frequencies need less MDS (more +number) due to an increase in atmospheric noise.)

IMDDR3 = 2 tone (20 kHz spacing) 3rd order Two tone IMD Dynamic Range. This test shows how the RX performs 
in the presence of multiple strong nearby signals in relation to its sensitivity (MDS). Higher is better. Pre-Amp Off 
 IMDDR3 numbers of +95dBm or more are considered excellent.

Ip3 = 2 tone (20 kHz spacing) 3rd order Intercept Point. This test also shows how the RX performs in the presence 
of multiple strong nearby signals. Higher is better. Pre-Amp OFF IP3 numbers of +15dBm are good, and +20dBm or
 more is excellent. Note: Low RX sensitivity can also artificially increase the measured Ip3.

Ip2 = 2 tone (8.020MHz, 6.000MHz) 2nd order Intercept Point This test shows how the RX performs in the presence
 of multiple strong out of band signals (such as broadcast signals on 6Mhz and 8Mhz creating birdies at 14Mhz).
 Higher is better. A Pre-Amp OFF IP2 of +55dBm is OK, and +70dBm or more is considered excellent.

BDR = Blocking Dynamic Range  (20 kHz spacing). This test shows when the receiver's sensitivity begins to drop
 in the presence of strong near by signals. (Desense). A Pre-Amp OFF BDR (20 kHz signal spacing) of greater than 
120dBm is good. Greater than 130dBm is considered excellent. BDR decreases as the interfering signal spacing from
 the receiver's listening frequency is reduced.

Phase Noise = value read from ARRL test graph at  +10 kHz from the carrier. Numbers are for the worst case band.
 Larger negative numbers are better. Bad phase noise contributes to poor RX Blocking Dynamic Range
 (desense from nearby signals.) Good values are  -120 dBc or better at +10 kHz. See the actual ARRL phase noise plots 
in each review for details of other spurious phase noise components.
