INFORMATION

GENERAL

0.01Hz to 20 kHz.

0.01Hz for frequencies up to 100 Hz,

0.1Hz for frequencies up to 1 kHz, 1 Hz for frequencies up to 20 kHz.

As frequency standard.

Less than 0.1% THD at 1 kHz.

Sine to 20 kHz, triangle or square wave to 3 kHz.

The modulation oscillator signal is available on a front-panel BNC connector at a level of 2 V RMS EMF from a 600 source impedance.

A front panel BNC connector is provided for external modulation input.

1 V RMS (1.414 V peak) sine wave for set deviation.

100 knominal.

The external modulation input can be leveled by a peak leveling ALC system over the input voltage range of 0.75 V to 1.25 V RMS sine wave. High and low indications are reported as part of the instrument status when the input is outside the leveling range.

A carrier frequency sweep mode is provided. The sweep is defined by setting the start, stop and frequency step size. The step time can be set from. A step or the complete sweep may be triggered by the trigger input on the front panel, VXI backplane trigger, message or VXI command. Sweep can be set to continuous.

Start/stop values of carrier frequency, size of step and time per step.

50 ms to 10 s per step.

Frequency step size of 1 Hz minimum.

Percentage increment of 0.01% to 50% in 0.01% steps. Single, continuous or external trigger.

A trigger input is available on a front-panel BNC. A step or the complete sweep may be triggered by the front-panel input, VXI backplane trigger or VXI command.

10 MHz.

Better than ±7 in 107 over the operating range 0 to 55°C. Less than ±1 in 106 per year.

Front-panel BNC connector accepts an input of 1 MHz or 10 MHz at 220 mV RMS to 1.8 V RMS into 1 k.

Complies with revisions 1.3 and 1.4 of the VXIbus specification for message-based instruments.

Manual selection (1 - 254).

A16 D16 message-based servant, programmable interrupter. Word serial IEEE 488.2. Fast handshake not supported. P1, P2 (highest slot of a 2-slot allocation).

Used to trigger sweep mode and step memory sequences. Not used.
