`
`Testing Conditions and Methods
`
`Suppliers shall demonstrate that the radio pager has been tested and certified
`to comply with the applicable technical requirements stipulated in section 2 of
`this Specification. Where applicable to the pager under test, measurement
`methods and conditions shall be as specified in this section.

`to 30°C and relative humidity from 65% to 85%.
`
`Voltages
`
`Voltages shall be as specified by the manufacturer. Pagers shall be expected
`to perform at nominal voltage down to -10% or just before low voltage alarm
`is sounded or indicated.
`
`Transmitter Test Requirements (applicable to 2-way radio pagers only)

`
`In the case of transmitter intended for use with an integral antenna, test
`fixture from the manufacturer shall be used for the relative measurements on
`the pager under test.
`
`The test fixture shall provide a 50 ohms terminal at the working frequencies of
`the transmitter.
`
`The test fixture shall provide means of making external connection to the
`radio frequency output.
`
`The performance characteristics of the test fixture shall be verified by the

`
`a.
`
`
`b.
`
`The coupling loss shall not be excessive, that is not greater
`than 20 dB.

`
`Pager Sensitivity
`3.4.1
`
`
`(This test includes the testing of IF Bandwidth to accommodate 1000 Hz "off-
`set" in the carrier frequency).
`
`
`Pager sensitivity is the measure of the minimum field strength that will cause
`the pager to receive from a signal at carrier operating frequency including
`"off-set" modulated by correct paging address and message, successfully at 5
`times out of 5 pages (100% SCR).

`
`The pager is being paged continuously at the rate of one
`message every 2 seconds for POCSAG receiver and 5
`seconds for FLEX receiver.
`
`The Signal Generator output level is decreased gradually in
`steps of 1.0 dB until a point where the pager could not receive
`the page or error message is received. At this point, the Signal
`Generator output level is increased in steps of 0.1 dB to a point
`where the pager could receive 5 consecutive pages without
`errors. This Signal Generator output level is noted.
`
`Repeat the test with the Signal Generator frequency adjusted
`to ±1000 Hz. There should be very little difference between all
`the output readings. The highest of all the reading shall be
`adopted.
`
`
`Limits
`3.4.1.3
`
`a.
`The minimum Field Strength for POCSAG receiver operating at
`512 bps shall be 5 μV/m; and operating at 1200 bps shall be 7
`μV/m.
`
`
`b.
`
`The minimum Field Strength for FLEX receiver operating at 6400
`bps shall be 10 µV/m.
`
`c.
`
`The above Field Strength limits may be adjusted to take
`account of pagers which are designed to be worn close to the
`human body (e.g. watch pagers) for added sensitivity. For such
`cases, the supplier shall state clearly the correction factor and

`Generator 1 is adjusted for the minimum pager sensitivity
`according to clause 3.4.1. This level is noted, and increased by
`3 dB.
`
`With Signal Generator 2 switched ON (unwanted signal), the
`frequency is set to the upper adjacent channel frequency.
`
`The output level of Signal Generator 2 is increased until the
`pager does not receive every call successfully.
`
`At this point the output level of Signal Generator 2 is reduced
`slowly until 5 times out of 5 calls are received without error.
`The RF level of Signal Generator 2 is noted.
`
`Steps (c) to (e) are repeated for the lower adjacent channel
`frequency.

`
`The ratio of the RF level of Signal Generator 2 to the RF level
`of Signal Generator 1 is the Adjacent Channel Selectivity. The
`lesser of the upper and lower adjacent channel frequency
`levels shall be used.
`
`Limits
`
`The limit of the Adjacent Channel Selectivity shall be no less than 55 dB.
`
`Spurious and Image Response Rejection
`
`Spurious and image response rejection is a measure of the capability of the
`pager to operate successfully from a wanted signal in the presence of a
`signal of any other frequency or the image frequency.
`

`
`With Signal Generator 2 switched OFF, output of Signal
`Generator 1 is adjusted for the minimum pager sensitivity
`according to clause 3.4.1. This level is noted, and increased by
`3 dB.
`
`With Signal Generator 2 switched ON, RF output is swept from
`30 to 1000 MHz (or 2600 MHz for IPS pagers) slowly. At any
`point where the paging calls of the pager appear to be
`interrupted, the RF output sweep is stopped. The output level
`is reduced until the pager is again able to response to pager
`calls of 5 times out of 5 pages successfully. This level is noted.
`
`Finally the frequency is adjusted to the image frequencies
`(Operating Frequency ±2 IF1 and Operating Frequency ±2 IF2),
`where IF1 is the 1st IF frequency and IF2 is the 2nd IF
`frequency.
`
`The spurious and image response rejection is the difference
`between the readings obtained from step (c) or (d) [the lower
`level shall be used] and step (b).
`
`Limits
`
`The limit of spurious/ image response rejection shall be no less than 50 dB.

`
`Intermodulation Response Rejection
`
`Intermodulation response rejection is a measure of the capability of a pager
`to inhibit the generation of a successful page response caused by two equal
`unwanted signals having specific frequency relationship to the nominal
`operating frequency, one of which is modulated with a normal coded test
`signal.

`adjacent channel frequency without modulation.
`
`Signal Generator 3 is switched ON and adjusted to 2 times the
`upper adjacent channel frequency.

`
`At this point the levels of both Signal Generators are reduced
`slowly until 5 times out of 5 calls are received without error.
`
`If necessary the frequencies of the two Signal Generators may
`be adjusted to obtain better response. This level is noted.
`
`Steps (c) to (f) are repeated for the lower adjacent channel
`frequency.

`
`Radiated Spurious Emission
`
`Radiated spurious emission from a pager is any emission radiated by the
`pager either by way of the integral antenna or radiated directly by the chassis
`and case of the pager.
`
`a.
`
`Method of measurement
`
`
`The pager shall be placed at a height of one metre from the
`ground in a room minimum size 5m x 3.2m x 2.6m on a non-
`conducting support vertically at a distance of 1 metre from the
`wall.
`
`

`
`c.
`
`
`d.
`
`
`e.
`
`
`f.
`
`
`g.
`
`
`h.
`
`The quarter-wave antenna attached to a suitable ground plane
`is placed at the same height 2 metres from the pager.
`
`The antenna is connected to the measuring receiver by a short
`piece of coaxial cable.
`
`The receiver is tuned, sweeping through the frequency range
`from 50 MHz to 1000 MHz (or 2000 MHz for IPS pagers).
`
`At each frequency where emission is detected the pager is
`rotated to get the maximum response. The frequency and
`received level is noted.
`
`After sweeping through the whole frequency range 50 MHz to
`1000 MHz (or 2000 MHz for IPS pagers) and noting all
`emission, the pager is replaced by an antenna connected to
`the signal generator.
`
`The frequency and level of the signal generator is adjusted to
`give the same reading on the measuring receiver as the
`emission that has been noted previously.
`
`The power radiated by the antenna fed from the signal
`generator is calculated from the signal generator output and
`these are the equivalent radiated emission from the pager.

`
`
`The occupied frequency range of the transmitter spectrum shall fall within the
`allocated frequency band. This is also valid at maximum frequency errors
`from the centre frequency of the band.
`
`Transmitting Power (ERP)
`
`Effective radiated power (ERP) refers to the product of the power supplied to
`the antenna and the maximum antenna gain relative to a half-wavelength
`dipole antenna. The permissible radiated power shall be the peak power, i.e.
`the power over the active part of a frame slot.

`bps bit stream.
`
`The transmitter power shall be measured using a spectrum
`analyzer with narrow
`frequency span and appropriate
`attenuation. Peak hold detection shall be used to centre the
`transmitting frequency of the test sample.
`
`Limits
`
`The effective radiated power at maximum output power (using the antenna
`gain recommended by the pager manufacturer) shall not exceed 1W.
`
`Frequency Stability
`
`Frequency stability is the ability of the transmitter to maintain the assigned
`frequency within the specified tolerance.
`
`Method of measurement
`
`The method of measurement is described in clause 3.5.2.1.
