The EUT has been programmed to continuously transmit during test. This operating condition was tested and used to collect the included data. b) The following table is the setting of the receiver Receiver Parameters Attenuation Start Frequency Stop Frequency IF Bandwidth Setting 10 dB 0.15 MHz 30 MHz 9 kHz c) The EUT was placed 0.8 meters from the horizontal ground plane with EUT being connected to the power mains through a line impedance stabilization network (LISN). All other support equipment powered from additional LISN(s). The LISN provide 50 Ohm/ 50uH of coupling impedance for the measuring instrument. d) Interconnecting cables that hang closer than 40 cm to the ground plane shall be folded back and forth in the center forming a bundle 30 to 40 cm long. e) I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the cable may be terminated, if required, using the correct terminating impedance. The overall length shall not exceed 1 m. f) LISN is at least 80 cm from nearest part of EUT chassis. g) For the actual test configuration, please refer to the related Item photographs of the test setup.

If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)). 5.9.2 Test Procedure a) Check the calibration of the measuring instrument using either an internal calibrator or a known signal from an external generator. b) Position the EUT without connection to measurement instrument. Turn on the EUT and connect its antenna terminal to measurement instrument via a low loss cable. Then set it to any one measured frequency within its operating range, and make sure the instrument is operated in its linear range. c) Set RBW to 100 kHz and VBW of spectrum analyzer to 300 kHz with a convenient frequency span including 100 kHz bandwidth from band edge. d) Measure the highest amplitude appearing on spectral display and set it as a reference level. Plot the graph with marking the highest point and edge frequency. e) Repeat above procedures until all measured frequencies were complete. 5.9.3 Test Setup EUT Spectrum Analyzer 5.9.4 Test Results Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com EUT: Pressure: Test plots - Page 49 of 74 - Report No.: HB20240402011E-01 Mini Pocket Printer 1012 hPa Model Name: Test Voltage: GFSK: Band Edge, Left Side S1 DC 3.7V from battery GFSK: Band Edge, Right Side Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com - Page 50 of 74 - Report No.: HB20240402011E-01 /4-DQPSK: Band Edge, Left Side /4-DQPSK: Band Edge, Right Side Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com - Page 51 of 74 - Report No.: HB20240402011E-01 8DPSK: Band Edge, Left Side 8DPSK: Band Edge, Right Side Add:Room 102, 201, Building 2, Yuanwanggu RFID Industrial Park, Tongguan Road, Tianliao Community, Yutang Street, Guangming District, Shenzhen,China Tel: (86-755) 29989321 Fax: (86-755) 29985110 Web:www.sz-hongbiao.com
