perpendicular  to  the  ground.  Connect  a  cable  between  the  antenna 
connector  and  the  receiver.  NOTE:  BE  SURE  TO  USE  A  CABLE  RATED 
FOR HIGH FREQUENCY WHEN OPERATING ABOVE 5 GHz (for example, 
the SAC-18G-3 or SAC-40G-1.5).

 

 

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.

 

 

TRIPOD AND MOUNTING ADPTERS 

ATU-510 Tripod 
AEH-510 Azimuth and Elevation Head 

The azimuth and elevation head (AEH-510) mounts to the tripod (ATU-510) 
top and allows the antennas to be rotated 360 degrees and tilted between 
horizontal  and  vertical  polarization.  The  tripod  and  azimuth  and  elevation 
head  come  in  their  own  carrying  case.  Each  tripod  leg  is  independently 
adjustable in angle and length to facilitate antenna height setting. The tripod 
legs have a rubber tip on one end for indoor or hard surface use, and a metal 
spike on the other end for outdoor soft surface (such as dirt) use. 
 

TRANSIT STORAGE CASES 

TCC-511 Tripod Carrying Case 
TSC-542 Transit Storage Case 

The  antenna  carrying  case  (TSC-542)  prevents  damage  and  loss  of 
antennas  when  storing  or  transporting  the  antenna  kit.  The  case  is 
constructed  of  lightweight  and  durable  polyethylene.  Two  case  keys  are 
provided with the case.
