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-510 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.

 

 

 
OPTIONAL EQUIPMENT 

 

The AK-40G case comes with three additional cutouts for optional preamplifiers. 
In  order  to  improve  overall  system  sensitivity,  the  following  equipment  will  be 
required: 
 

  PAM-0118 with an SAC-18G-0.5 

 

PAM-1840 with an SAC-40G-0.5

 

 

PAM-0118P Preamplifier 20 MHz 

– 18 GHz

 

The  preamplifier  will  increase the system  sensitivity  37  dB  and  is recommend  for 
the SAS-510-2, SAS-530,542 and SAS-571. An optional short length cable (SAC-
18G-0.5),  is  required  to  connect  the  preamplifier  to  any  50-ohm  receiver  or 
spectrum analyzer.
