Analog Interface Specifications

Parameter Details min typ max
number of input and output - 4    
connectors of input and output - SMA, front panel single-ended    
impedance of input and output - 50 Ω    
input and output frequency range    
frequency range of I and Q input - DC - 6 GHz
frequency range of LO input and RF output calibration and RF mode 4 GHz - 8 GHz
frequency range of LO input and output LO mode 1.8 GHz - 10 GHz
input and output power    
I and Q input 1 dB input compression point1 for the instrument with the serial number below 14100 - 0 dBm -
  for the instrument with the serial number 14100 and above - +10 dBm -
LO input 1 dB input compression point calibration and RF mode - +6 dBm -
LO input power calibration and RF mode +1 dBm +5 dBm +7 dBm
  LO mode - - +7 dBm
attenuation of LO output power (representation)(PLO, input/PLO, Exp., output) LO mode - 16 dB -
RF output 1 dB output compression point1 calibration and RF mode, see in this figure - +5 dBm -
conversion gain (PRF, Exp./PI or PRF, Exp./PQ) for the instrument with the serial number below 14100, measured at 4 GHz - +5 dB -
  for the instrument with the serial number 14100 and above, measured at 4 GHz - -5 dB -
Crosstalk RF mode - -65 dB -50 dB (8.0 GHz)
LO leakage and image sideband suppression    
LO leakage suppression after mixer calibration - - -55 dBc
sideband suppression after mixer calibration - - -55 dBc
SFDR after mixer calibration 40 dBc - -
Phase noise    
phase noise PLO = 5 dBm, PI/Q = 5 dBm, fI/Q = 100 MHz see in this figure    
operating modes    
switchable operating modes - calibration, RF and LO    
RF switches    
LO isolation (PLO,input /PLO,Exp. ) RF mode > 57 dB    
switching time - < 0.1 s    

1 Operating up to +1 dBm of the compression point still yields reasonable linearity and SFDR as in the above table, since the compression point is limited by the amplification stage and not by the mixer component itself.
