assembly. Connect a cable between the antenna connector and the receiver. The 
broadband dipole beam pattern is similar to a dipole response.

 

 

SAS-542 Biconical Antenna 20 MHz - 330 MHz 

 

The  biconical  antenna  consists  of  the  SAS-542  balun  assembly  and  two  folding 
biconical elements. 

 

Operation:

  Attach  the  balun  assembly  to  the  tripod  thru  the  screw  hole  in  the 

balun  assembly  base.  Screw  the  two  biconical  elements  into  the  'tee'  end  of  the 
balun  assembly.  Open  the  antenna  elements  completely  and  secure  in  open 
position  by  tightening  the  knurled  knobs  in  the  element  caps.  Connect  a  cable 
between  the  antenna  connector  and  the  receiver.  The  biconical  beam  pattern  is 
similar to a dipole response.

 

 

SAS-550-1B Active Monopole Antenna 10kHz - 60 MHz 

 

The active monopole antenna consists of a ground plane upon which are mounted 
a preamplifier with internal rechargeable battery pack for battery operation, and a 
telescoping rod antenna. 

 

Operation:

  Mount  the  antenna  on  the  tripod.  Connect  an  external  ground  to  the 

ground  plane  if  called  out  in  test  specification.  Attach  the  telescoping  rod  to  the 
connector  on  the  amplifier  top  and  extend  fully.  Connect  the  output  on  amplifier 
side to the receiver using a cable. Apply power to antenna (turn battery power 'on'. 
The active monopole antenna is omni-directional.

 

 

 

 

MAGNETIC LOOP ANTENNA 

 

SAS-560 Magnetic Loop Antenna 20 Hz - 2 MHz 

 

The loop antenna does not require any assembly. 

 

Operation:

 The loop antenna is designed to be held by hand and moved around 

each surface if the EUT to measure magnetic radiation. Connect the antenna via a 
cable  to  a  receiver  with  either  a  50  ohm  input  or  high  impedance  (10  K  ohm  or 
greater) input. Calibrations for both inputs are provided.

 

 
 

 
 
CURRENT PROBES 

 

BCP-610 LF Current Probe 20 Hz - 20 MHz  
BCP-611 HF/VHF Current Probe 10 kHz - 150 MHz 

 

The current probes come ready for use. 

 

Operation:

 The two current probes measure conducted emissions when clamped 

around a single conductor, cable or a bundle of conductors. Disconnect the probe 
latch Position the probe around the conductor and close the probe. Reconnect the 
probe latch to ensure that the probe is tightly closed. Connect the probe connector 
to  the  receiver  with  a  cable.  The  probe  calibrations  supplied  are  into  a  50-ohm 
receiver.
