Measuring AGC threshold level Power and Conducted RF Output 4.1 Test Procedure according to KDB935210 D5 3.2 a) Connect a signal generator to the input of the EUT. b) Connect a spectrum analyzer or power meter to the output of the EUT using appropriate attenuation as necessary. c) The signal generator should initially be configured to produce either of the required test signals (i.e., broadband or narrowband). d) Set the signal generator frequency to the center frequency of the EUT operating band. e) While monitoring the output power of the EUT, measured using the methods of 3.5.3 or 3.5.4, increase the input level until a 1 dB increase in the input signal power no longer causes a 1 dB increase in the output signal power. f) Record this level as the AGC threshold level. g) Repeat the procedure with the remaining test signal. 2.

ESTECH CO., LTD. FCC ID : N52-SDR-ICS-437FN http://www.estech.co.kr 5. Occupied Bandwidth 5.1 Test Procedure according to KDB935210 D5 3.4 a) Connect a signal generator to the input of the EUT. b) Configure the signal generator to transmit the AWGN signal. c) Configure the signal amplitude to be just below the AGC threshold level (see 3.2), but not more than 0.5 dB below. d) Connect a spectrum analyzer to the output of the EUT using appropriate attenuation. e) Set the spectrum analyzer center frequency to the center frequency of the operational band under test. The span range of the spectrum analyzer shall be between 2 times to 5 times the emission bandwidth (EBW) or alternatively, the OBW. f) The nominal RBW shall be in the range of 1 % to 5 % of the anticipated OBW, and the VBW shall be ≥ 3 × RBW. g) Set the reference level of the instrument as required to preclude the signal from exceeding the maximum spectrum analyzer input mixer level for linear operation. In general, the peak of the spectral envelope must be more than [10 log (OBW / RBW)] below the reference level. Steps f) and g) may require iteration to enable adjustments within the specified tolerances. h) The noise floor of the spectrum analyzer at the selected RBW shall be at least 36 dB below the reference level. i) Set spectrum analyzer detection function to positive peak. j) Set the trace mode to max hold. k) Determine the reference value: Allow the trace to stabilize. Set the spectrum analyzer marker to the highest amplitude level of the displayed trace (this is the reference value) and record the associated frequency as f0. l) Place two markers, one at the lowest and the other at the highest frequency of the envelope of the spectral display, such that each marker is at or slightly below the −26 dB down amplitude. The 26 dB EBW (alternatively OBW) is the positive frequency difference between the two markers. If the spectral envelope crosses the −26 dB down amplitude at multiple points, the lowest or highest frequency shall be selected as the frequencies that are the furthest removed from the center frequency at which the spectral envelope crosses the −26 dB down amplitude point. m) Repeat steps e) to l) with the input signal connected directly to the spectrum analyzer (i.e., input signal measurement). n) Compare the spectral plot of the input signal (determined from step m) to the output signal (determined from step l) to affirm that they are similar (in passband and rolloff characteristic features and relative spectral locations), and include plot(s) and descriptions in test report. o) Repeat the procedure [steps e) to n)] with the input signal amplitude set to 3 dB above the AGC threshold. p) Repeat steps e) to o) with the signal generator set to the narrowband signal. q) Repeat steps e) to p) for all frequency bands authorized for use by the EUT.

Out of Band Rejection 6.1 Test Procedure a) Connect a signal generator to the input of the EUT. b) Configure a swept CW signal with the following parameters: 1) Frequency range = ± 250 % of the passband, for each applicable CMRS band (see also KDB Publication 935210 D02 [R7] and KDB Publication 634817 [R5] about selection of frequencies for testing and for grant listings). 2) Level = a sufficient level to affirm that the out-of-band rejection is > 20 dB above the noise floor and will not engage the AGC during the entire sweep. 3) Dwell time = approximately 10 ms. 4) Number of points = SPAN/(RBW/2). c) Connect a spectrum analyzer to the output of the EUT using appropriate attenuation. d) Set the span of the spectrum analyzer to the same as the frequency range of the signal generator. e) Set the resolution bandwidth (RBW) of the spectrum analyzer to be 1 % to 5 % of the EUT passband, and the video bandwidth (VBW) shall be set to ≥ 3 × RBW. f) Set the detector to Peak Max-Hold and wait for the spectrum analyzer’s spectral display to fill. g) Place a marker to the peak of the frequency response and record this frequency as f0. h) Place two markers, one at the lowest and the other at the highest frequency of the envelope of the spectral display, such that each marker is at or slightly below the −20 dB down amplitude, to determine the 20 dB bandwidth. i) Capture the frequency response of the EUT. j) Repeat for all frequency bands applicable for use by the EUT.

Spurious Emission at Antenna Terminal 7.1 Test Procedure a) Connect a signal generator to the input of the EUT. b) Set the signal generator to produce the broadband test signal as previously described (i.e., 4.1 MHz OBW AWGN). c) Set the center frequency of the test signal to the lowest available channel within the frequency band or block. d) Set the EUT input power to a level that is just below the AGC threshold (see 3.2), but not more than 0.5 dB below. e) Connect a spectrum analyzer to the output of the EUT using appropriate attenuation as necessary. f) Set the RBW = reference bandwidth in the applicable rule section for the supported frequency band of operation (e.g., reference bandwidth is typically 100 kHz or 1 MHz). g) Set the VBW ≥ 3 × RBW. h) Set the Sweep time = auto-couple. i) Set the spectrum analyzer start frequency to the lowest RF signal generated in the equipment, without going below 9 kHz, and the stop frequency to the lower band/block edge frequency minus 100 kHz or 1 MHz, as specified in the applicable rule part. The number of measurement points in each sweep must be ≥ (2 × span/RBW), which may require that the measurement range defined by the start and stop frequencies be subdivided, depending on the available number of measurement points provided by the spectrum analyzer.4 j) Select the power averaging (rms) detector function. k) Trace average at least 10 traces in power averaging (rms) mode. l) Use the peak marker function to identify the highest amplitude level over each measured frequency range. Record the frequency and amplitude and capture a plot for inclusion in the test report. m) Reset the spectrum analyzer start frequency to the upper band/block edge frequency plus 100 kHz or 1 MHz, as specified in the applicable rule part, and the spectrum analyzer stop frequency to 10 times the highest frequency of the fundamental emission (see Section 2.1057). The number of measurement points in each sweep must be ≥ (2 × span/RBW), which may require that the measurement range defined by the start and stop frequencies be subdivided, depending on the available number of measurement points provided by the spectrum analyzer. n) Trace average at least 10 traces in power averaging (rms) mode. o) Use the peak marker function to identify the highest amplitude level over each of the measured frequency ranges. Record the frequency and amplitude and capture a plot for inclusion in the test report; also provide tabular data, if required. p) Repeat steps i) to o) with the input test signals firstly tuned to a middle band/block frequency/channel, and then tuned to a high band/block frequency/channel. q) Repeat steps b) to p) with the narrowband test signal. r) Repeat steps b) to q) for all authorized frequency bands/blocks used by the EUT.

Radiated Spurious Emission 8.1 Test Procedure according to KDB935210 D5 3.4 This measurement is intended to produce test data necessary to demonstrate compliance to the radiated spurious emission requirements specified in Section 2.1053 of the FCC rules. This test is intended to capture any emissions that radiate directly from the case, cabinet, control circuits, etc., instead of via the antenna output port, and thus would not be captured in conducted spurious emission measurements.
