Please can anyone help us....

We are experiancing problems, trying to measure a 20MHz Crystal connected to a Renesas H8/3687 micro processor.

Whenever we attempt a reading on our Agilent i3070 machines (Un-multiplexed Hybrid 144-Channel cards) the crystal shuts down. Our current program is set up as follows:

!!!!    2    0    1 1219668327  V3aac                                        
! IPG: rev 07.00p  Mon Aug 25 22:45:28 2008

! 20Mhz

test powered analog
   test "Pin1"
   test "Pin2"
end test

!-----------------------------------------------------------------------
subtest "Pin1"
   F=20M
   connect rcva to pins 1               ! Output
   detector frequency, expect F, threshold 1
   measure F*1.1, F*0.9
end subtest

subtest "Pin2"
   F=20M
   connect rcva to pins 2               ! Output
   detector frequency, expect F, threshold 1
   measure F*1.1, F*0.9
end subtest


Many thanks
