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 Ω

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

Impedance: 50 Ω nominal

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

Impedance: 50 Ω 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
