Reference Speciﬁcations

Reference Specifications

The accuracy needs for testing GSM radios require the unit to be operated with

the high stability reference (option 001) or an external high stability reference.

Accuracy (after warm up): ± [(Time since calibration x aging rate) +

temperature effects + accuracy of

calibration]

External reference input Frequency: 13, 10, 5, 2 or 1 MHz, ± 30 ppm

Level: 0 to +10 dBm

Supplemental characteristics

Nominal impedance: 50 ohm

10 MHz out (rear panel BNC) Level: > +8.0 dBm nominal

Impedance: 50 ohm nominal

13 MHz out (rear panel BNC) Level: > +8.0 dBm nominal

Impedance: 50 ohm nominal

Fixed reference mode

Aging: < 2 ppm/year

Temperature stability: ± 1 ppm (0˚ to 55˚C)

Warm-up time: < 30 minutes, ± 2 ppm of ﬁnal frequency

Tunable reference mode

This allows offsetting the internal reference by a selected amount relative to the

high stability reference (option 001) or an external reference.

Required external reference accuracy: ± 0.5 ppm

Tune range: ± 30 ppm

Reference accuracy: ± 1 ppm + accuracy of external reference

or high stability (option 001)

Temperature stability: ≤ 4 ppm, for selected offsets of up to

± 30 ppm
