1.3 Insertion loss 
 

The insertion loss of the Pulse Limiter is calibrated in a 50 ohm system over 
the frequency range of 9 kHz to 30 MHz, and is 0.4 dB maximum. 
 

1.4 Environment 

The operating environment is specified to be within the following limitations: 

 

  Temperature  

  Humidity 

 

0° to +45° C 
< 90% relative 
 

 

The instrument should be stored in a clean, dry environment 
The storage and shipping environment is specified to be within the following 
limitations : 

 

  Temperature  

  Humidity 

 

-25° to + 70° C 
< 95% relative 

1.5 Return for service 

If the instrument should be returned to NARDA for service, please complete 
the service questionnaire enclosed with the Operating Manual and attach it 
to the instrument. 
To minimize the repair time, be as specific as possible when describing the 
failure.  If  the  failure  only  occurs  under  certain  conditions,  explain  how  to 
duplicate the failure. 
If  possible,  reuse  of  the  original  packaging  to  ship  the  equipment  is 
preferable.  
In  case  other  package  should  be  used  ensure  to  wrap  the  instrument  in 
heavy paper or plastic. 
Use a strong shipping container and use enough shock absorbing material 
around  all  sides  of  the  equipment  to  provide  a  firm  cushion  and  prevent 
movement in the container. 
Seal the shipping container securely with shipment tape. 
Mark the shipping container FRAGILE to encourage careful handling.
