September 11, 2002 Page 1 of 3 Re: FCC ID QF7INTERRAGATOR Applicant: Geophysical Survey Systems, Inc. Correspondence Reference Number: 23858 731 Confirmation Number: EA363608 1) Please characterize the pulse. What is the pulse width? What is the frequency of the pulse? Or is the frequency of the pulse pseudorandom? A photo of the pulse is given below. The pulse width is approximately 3 ns. The PRF is a fixed 100 KHz. There is no randomizing. This picture has the antenna 1 meter above a reflective plate. The first pulse is the direct coupling between transmitter and receiver, and the second pulse is that reflected from the plate. The horizontal scale is in nanoseconds. September 11, 2002 Page 2 of 3 3) Upload a plot and table of data to show the -10 dB points. The plot should consist of max hold PEAK detector field strength level measured in any direction versus frequency. The field strength measurement for these points must account for non-linearities across the band that would be on the spectrum plot (ie: antenna and amplifier is not equal across the band). Ensure that the frequency range tested is wide enough to include the widest points of the electronic signature that are 10 dB down from the highest peak level. Do not use Horn antennas since Horn antennas are mounted 1 meter above the ground are directed above the EUT. All of our data has already been corrected for antenna, amplifier, cables, etc. The resulting spectrum is attached. As seen from the plot and table below, the peak is at 70.31 MHz, and the –10dB point is at 889.5 MHz. All of this data was taken with the log-periodic antenna.

While photographing the sample board without the shield, it was discovered that one of the original photographs was mis-labeled. The complete set of all photographs is attached as INTERRAGATOR INTERNAL PHOTOS REV B.pdf. 7) Indicate compliance with 15.503(f). Attached are the first two pages of the user’s manual indicating compliance with 15.503(f).

To: Joe Dichoso FCC Application Processing Branch Re: FCC ID QF7INTERRAGATOR Applicant: Geophysical Survey Systems, Inc. Correspondence Reference Number: 23929 731 Confirmation Number: EA363608 1) The pulse has no carrier frequency. The pulse repetition frequency is fixed at 100kHz. A plot and description of the pulse width and repetition is provided by GSSI contained in new Cover Letter exhibit - file name “QF7Interragator questions 2.pdf” 2) Additional measurements were made in the frequency range of 960-1000MHz using a log periodic antenna. A revised test report has been uploaded with file name Interragator_Report_RevD.pdf (p14) 3) GSSI has verified the product frequency range as 30 – 889.5MHz in the new Cover Letter exhibit - file name “QF7Interragator questions 2.pdf” 4) The Interragator is designed to work only in contact with the ground, has a ‘dead-man’ switch and is shielded to direct the energy into the ground. A full description and photographs are contained in the new Cover Letter exhibit - file name “QF7Interragator questions 2.pdf” 5) A photograph of the label location is contained in the new Cover Letter exhibit - file name “QF7Interragator questions 2.pdf”

To: Alan Schutz, Geophysical Survey Systems Inc From: Joe Dichoso [email protected] FCC Application Processing Branch Re: FCC ID QF7INTERRAGATOR Applicant: Geophysical Survey Systems, Inc. Correspondence Reference Number: 23929 731 Confirmation Number: EA363608 1) What is the carrier frequency of the pulse? There is no carrier. It is a single cycle, whose center frequency is approximately 300 MHz. A photo of the pulse is given below. The pulse width is approximately 3 ns. The PRF is a fixed 100 KHz. There is no randomizing. This picture has the antenna 1 meter above a reflective plate. The first pulse is the direct coupling between transmitter and receiver, and the second pulse is that reflected from the plate. The horizontal scale is in nanoseconds. 2) Measurement from 960 -1 GHz with a log periodic antenna was requested due to the margin of compliance at 960 MHz which was 1 dB from the limit. When testing with a horn antenna, the horn antenna is focused 1 meter above your device and therefore it may not capture ground reflection as well as a log periodic antenna. Provide data at 960 MHz additional testing may be required depending on results or margin of compliance. 3) The requested frequency range will be changed to 30-889.5 MHz. Please verify. Yes, we agree. 4) With regard to compliance with 15.503(f), the device must be designed to operate when in contact with the ground and have shielding to direct emissions toward the ground. In addition, imaging systems must have a manual switch which causes the transmitter to cease within 10 seconds. Please address these 3 issues. The Interragator is a cart-like device that is rather heavy. It can only be used on the ground. The antenna is constructed as a five-sided metal box, with the antenna fans in the sixth side, on the ground side. The non-transmitting electronics is placed on the top of the shield. Another shield is placed over the electronics. There is a deadman switch on the handle. When the user steps away from the cart, the transmitter will cease operating after 10 seconds. A drawing of the deadman switch is given on the next page. 5) For compliance with 15.509(g), the label information must be on the device. Show where this label will be placed on the device.
