Specifications are from and may vary slightly due to upgrades. Options, or revisions this unit may or may not have. This set is guaranteed to work for 30-days. Parts and labor, excluding freight. Link to the Manual: Link to the Manual: Description: An HP 339A with Option 001 installed is a standard 339A Distortion Measurement Set with two additional voltmeter input ranges. These ranges are.3 mV and.1 mV full scale. Measurement capabilities are from.1 mV rms full scale to.3 mV rms full scale in a frequency range of 10 Hz to 80 kHz. And from.001 V rms full scale to 300 V rms full sclae in a frequency range of 10 Hz to 110 kHz. When switched to the.3 mV range. The voltmeter attenuator is set to 0 dB. When switched to the.1 mV range, the voltmeter attenuator remains at 0 dB and 10 dB of gain is added to the input amplifier. This gives the required input for full scale deflection on the front panel voltmeter. These changes in voltmeter range have been accomplished by adding two additional positions on S4 of the Analyzer/Power Supply printed circuit assembly. Distortion Specifications: Fundamental Frequency Range: 10 Hz to 110 kHz continuous frequency coverage in 4 decade ranges with 2-digit resolution. Distortion analyzer and oscillator are simultaneously tuned. Distortion Measurement Range: 0.01% full scale to 100% full scale(80 dB to 0 dB) in 9 ranges. Detection and Meter Indication: True rms detection for waveforms with crest factor Option 001 Specifications: Voltage Range: Standard: 1 mV rms full scale to 300 V rms full scale(60 dB to +50 dB full scale. Meter calibrated in dBV and dBm into 500 ohm) Option 001: 1 mV rms full scale to 300 V rms full scale(80 dB to +50 dB full scale.
