To the Reviewer: I incorrectly specified the frequency range of operation on the Form 731. It should read “0.1 – 900 MHz” as the frequency range of operation of the EUT. I was deriving my information from an incorrect source. Please amend the certification to reflect this.

To: Alan Schutz, Geophysical Survey Systems Inc From: Andy Leimer [email protected] FCC Application Processing Branch Re: FCC ID QF75106 Applicant: Geophysical Survey Systems, Inc. Correspondence Reference Number: 23481 731 Confirmation Number: EA740530 1) More information is needed on the 0.5 ns pulse. Is the pulse pseudo random (dithered) or is it periodic (You mentioned a maximum PRF of 100 kHz). Upload a plot of the pulse. The pulse is not dithered, it is a fixed frequency. 100 KHz is the maximum allowable PRF because that is the frequency at which the emissions test was performed. The picture below shows the shape of the pulse. (The horizontal scale is in ns.) 2) Measurements from 960 MHz to 1 GHz were done using a horn antenna. Remeasure this band using a bicon antenna. The horn antenna is calibrated down to 900MHz so the bicon should not be necessary. There are no emissions above 960 that are not related to the UWB transmission so no quasi-peak data is presented. To cover the entire range from 30 MHz to 10 GHz, two different setups were used, including changing the analyzer, antenna, cables, preamp and procedure. If we can’t use the horn between 960 and 1000, then a third setup is required. 3) It appears that there is no shielding above the antenna. What measures have been taken to ensure that the emissions from the top of the device are less than the ground penetrating emissions. The antenna is entirely within a shielded metal box. Only the bottom is open (where the fans are). 4) There is a procedure in the test report for the -10 dB points but no data or plots. Upload a spectrum plot and data for the -10 dB points. I suggest a field strength measurement for these points to account for non-linearities across the band that would be on the spectrum plot (ie: antenna and amplifier is not equal across the band). From the plot below, the peak is at 224 MHz. The lower –10 dB point is 112 MHz. The upper –10 dB point is 316 MHz. All data has already been corrected for antenna, amplifier, cables, etc. The data tables are in the test report. 5) What type of imaging system is this (low, mid, or high frequency). What is the center frequency? This is a low frequency system. The center frequency is 214 MHz. 6) Heading missing on some test data tables. Upload corrected tables with the proper headings as shown in Table 1 of the Test Data. 7) The formula used for determining RMS level of the emission is not clear. Show how this was derived. Upload all data used for this calculation and provide a sample calculation. The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 60 days of the original e-mail date may result in application dismissal pursuant to Section 2.917 (c) and forfeiture of the filing fee pursuant to section 1.1108. DO NOT reply to this e-mail by using the Reply button.

Correspondence Reference Number: 23663 731 Confirmation Number: EA740530 5) Your response indicated that there is shielding above the antenna. How much shielding is provided and how effective is it in ensuring that the energy from the GPR is directed down into the ground as required in Part 15.503(f). It is recommended that you submit a field measurement from the top of the device showing compliance with the limit. This can be done by suspending an antenna above the device or by turning it on it's side and doing a table top test. 5) The shielding is a five-sided aluminum box. The emissions test had the receiving horn vary from 1 meter to 4 meters above the DUT. This has demonstrated that the shielding is sufficient to keep the air emissions below the spec curve. Photos of the top and bottom of the shield are shown below.
