FM-AM Signal Generator 102A

Range:
4.3 to 520 MHz in 5 bands: Band 1-4.3 to 37.5 MHz; Band 2-32.5 to 65 MHz; Band 3-65 to 130 MHz; Band 4-130 to 260 MHz; and Band 5-260 to 520 MHz.

Accuracy: ±(100 Hz +3 ppm at 20 to3 0°C; can be readjusted to an external frequency standard.

Resolution:  Selectable, 0.1 kHz, 1 kHz, or 10 kHz.
Display: 6-digit LED.

Stability
Bands 2 through 5: Drift less than 20 ppm/10 min after 1 hour warmup (typically, less than 10 ppm/10 min after 2 hour warmup, and less than 2 ppm/10 min after 4 hour warmup.
Band 1: Drift less than 1.5 kHz/10 min after 1 hour warmup.

Fine Tuning: Electronic vernier, approximate range of 12.5 kHz on bands 1 and 2.25 kHz on band 3.50 kHz on band 4, and 100 kHz on band 5.

Residual FM: Less than 20 Hz peak, band 1; less than 0.25 ppm peak, bands 2 through 5 (both in 20 Hz to 15 kHz post-detection bandwidth).

Power Level: -130 dBm to +13 dBm (0.07 microvolt to 1 volt into 50 ohms).
Attenuator: 13 steps in 10 dB / step plus variable 13 dB calibrated on output meter.
Accuracy: +(1.0 dB+attenuator accuracy) (Attenuator accuracy is 0.1 dB / 10 dB step, with maximum cumulative error of +- 1.0 dB).

Leveling: -0.5 dB maximum variation across each band.

Spurious Outputs: Harmonics, better than -30 dB Sub-harmonically related, better than -40 dB Mixing products (band 1), better than -30 dB.
(All at settings between 0 and -10 dBm on output vernier range).

Impedance: 50 ohms, with VSWR less than 1.5:1 at levels below 0 dBm.

Single Sideband Phase Noise: Bands 1 through 3, more than 120 dB/Hz below carrier (typically 125 dB/Hz, 20 kHz off carrier) Bands 4 and 5, more than 105 dB/Hz below carrier (typically 115 dB/Hz, 20 kHz off carrier).

Single Sideband Noise Floor: Typically 130 dB/Hz below carrier.
