FCC ID: QQ7EGUARDEAS01 Circuit Description The 8.5MHz LCR oscillator drives the base of Q2 the final/buffer amplifier. The modulation provided by V4. The output of Q2 has the matching network consisting of L9 and C39 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 117Va.c. – 22Vd.c. adaptor.

1 Marianne Bosley From: Marianne Bosley Sent: Thursday, January 02, 2003 10:34 AM To: '[email protected]' Subject: Request for Technical Info for FCC ID:QQ7EGUARDEAS01 Hi Alice, Below are the technical issues that must be addressed before grant: RT questions: Was the frequency sweep stopped while radiated measurements were made? What is the frequency range of the sweep? Does the EUT employ an analog sweep (continuous, sliding over all frequencies in the band) or a digital sweep (discrete frequencies hopped to very rapidly)? If it is a digital sweep (as most modern systems are), then none of the discrete frequencies on which it lands may be in a restricted band, as defined in Section 15.205. What discrete frequencies are used? Please address. Was a loop antenna used for radiated measurements? If not, please remeasure with a loop antenna- a rod antenna may not be used. If so, was it both rotated on its vertical axis AND placed in the horizontal plane as well, per ANSI C63.4 Section 8.2.1? The “correction factors” listed in the radiated emissions data table seem quite low for the antenna, compared to those used for many loop antennas. Please address. When calculating the duty cycle correction factor, please note the following: a duty cycle correction factor is NOT applied to an analog system For digital systems, the averaging factor described in Section 15.35 may be applied, based upon how much time the signal actually spends on each discrete channel during a 100 ms interval. If the EUT goes through its hopset and returns to the same frequency during the 100 ms interval, then the total occupancy time on that frequency during the 100 ms interval should be used in calculating the duty cycle correction. Note that if the hopping frequency channels are so close that more than one of them falls within the 9 kHz bandwidth required for measurements, then the duty cycle correction must include the total time spent on all of the channels within that 9 kHz band during the 100 ms measurement interval. Please address. When these are addressed the grant will be issued. Marianne Bosley

1 Marianne Bosley From: Marianne Bosley Sent: Thursday, January 30, 2003 9:37 AM To: '[email protected]' Subject: Shenzhen Ronghua Electronic Co Ltd. - FCC IDs: QQ7EGUARDEAS01 and QQ7EGUARDEAS02 Hello again, Below is the response from the engineer. He is asking for more clarification: Even though the EUT transmits continuously along its sweep, it is possible that the sweep actually consists of the fundamental emission being quickly tuned to specific, predetermined frequencies. Our experience shows that most of the newer swept frequency devices operate along this principle. The manufacturer should be able to tell you if this is the case, in which case he should also provide for you the actual frequencies to which the EUT tunes. None of these may be located in a restricted band, as defined in Section 15.205. It is possible that an older, true analog sweep is being used, in which case Section 15.205(d)(1) must be addressed (demonstrating that the sweep spends less than 1% of its time in any restricted band).

Close From: Greg Czumak To: Marianne Bosley; Chris Harvey; TCB INFO Cc: Subject: RE: Metrak 13228 FCC ID: QQ7EGUARDEAS02 and Metrak 13235 FCC ID:QQ7EGUARDEAS01 (Shenzhen Ronghua Electronic Co Ltd.) Sent: 4/29/2003 11:02 AM Importance: Normal I have reviewed the latest responses. It appears that new tests were performed, as results are different from the original test report. If this the case, they again made several of the same omissions made in the first report, about which I had to query them. They also have still not answered the one question for which I was awaiting a response since last January. I also note that this new report is for the '01. There is still no response wrt the '02. RT questions below. RT questions: 1. The latest test report indicates a tuning range that is different from that which was originally reported. Also, the field strength measurements have different results. A number of the original questions are again unanswered. If the EUT tunes to discrete, predetermined frequencies, what are they? The FCC does not allow any such frequencies to be located in a restricted band, as defined in Section 15.205. If the EUT uses a continuous (analog) sweep, then please demonstrate compliance with Section 15.205(d)(1). 2. Was the loop antenna, used for radiated emission testing, rotated 360 degrees on its vertical axis, and then placed horizontally, pursuant to C63.4 Section 8.2.1? 3. I note that this test report is for FCC ID: QQ7EGUARDEAS01.
