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
A front panel BNC connector is provided for external modulation input.
1 V RMS (1.414 V peak) sine wave for set deviation.
100 kΩ nominal.
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
10 MHz.
Better than ±7 in 107 over the operating range 0 to 55°C. Less than ±1 in 106 per year.
Complies with revisions 1.3 and 1.4 of the VXIbus specification for
Manual selection (1 - 254).
