Section 2: Equipment Under Test

2.1   Theory of Operation

The TZ43TZW005 is a Thermostat. Its function is to communicate set point data with a
furnace or air conditioner system. Unterminated typical wiring was added to ensure
worst case spurious emissions. The EUT was exercised by an internal test program set
to transmit with continuous modulation for RF testing.

The EUT’s performance during test was evaluated against the performance criterion
specified by applicable test standards. Performance results are detailed in the test
results section of this report.

15.215(c) Intentional radiators operating under the alternative provisions to the general emission limits,
as contained in Sec. Sec. 15.217 through 15.257 and in Subpart E of this part, must be designed to
ensure that the 20 dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in
the specific rule section under which the equipment operates, is contained within the frequency band
designated in the rule section under which the equipment is operated. The requirement to contain the
designated bandwidth of the emission within the specified frequency band includes the effects from
frequency sweeping, frequency hopping and other modulation techniques that may be employed as well
as the frequency stability of the transmitter over expected variations in temperature and supply voltage.
If a frequency stability is not specified in the regulations, it is recommended that the fundamental
emission be kept within at least the central 80% of the permitted band in order to minimize the possibility
of out-of-band operation.

Test Results:

      See Table. EUT complies for fundamental power, bandedges and spurious
      emissions.

Additional Observations:

      The Spectrum was searched from 30MHz to the 10th Harmonic (9280 MHz).

      These results apply to emissions that may be found in the restricted bands
      defined in FCC Part 15 Subpart C, 15.205. The EUT was investigated with a
      variac that showed no output power differences when the line voltage was
      varied by +/- 15 % of nominal 120 Vac.

      All Measurements below 1GHz were performed at 3m employing a CISPR
      quasi-peak detector, except for the radio’s fundamental. Peak
      measurements above 1GHz were done utilizing RBW of 1MHz and VBW of
      3MHz. Average measurements above 1GHz were done utilizing RBW of
      1MHz and VBW of 10Hz as the duty cycle was 100%.

      Measurements made at the 3 meter Outside Area Test Site, all
      measurements max hold after peaking for EUT rotation and antenna height
      from 1 to 4 meters.

      Fundamental power was measured at 1 MHz RBW, 3 MHz VBW to ensure
      capture of entire emissions envelope. 15.249(e). And the peak field
      strength of any emission shall not exceed the maximum permitted average
      limits specified above by more than 20 dB under any condition of
      modulation. The peak field strength emission passes when measured at
      max hold RBW of 1 MHz with 3 MHz VBW.

      No other emissions found within 20 dB of the limits.
