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 < or = to 3. Meter reads dB and % THD (Total Harmonic Distortion). Meter response can be changed from NORMAL to VU ballistics with a front panel switch.
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, meter calibrated in dBV and dBm into 600 ohm).

< -92 dB referenced to 1 V.
Input Level for Distortion Measurement:
30 mV to 300 V rms (100 mV range minimum)
Input Impedance:
100 kΩ ±1.0% shunted by < 100 pF input High to Low.
DC Isolation:
Input low may be connected to chassis ground or floated 30 V to reduce the effects of ground loops on the measurement.
Auto Set Level:
No set level adjustment required. Distortion measurements are made directly over 10 dB range selected by input range switch. Two LED annunciators provide a fast visual indication to change input range for valid distortion measurement. Correct range is indicated when both annunciators are extinguished.
Auto Null:
Using Internal Oscillators:
No manual frequency tuning necessary when using internal oscillator as signal source. Oscillator frequency controls simultaneously tune the analyzer.
Using External Frequency Source:
Two LED annunciators provide a quick visual indication for the operator to increase or decrease the analyzer frequency controls. When the analyzer is rough tuned to within one least significant digit of the fundamental frequency, the indicator lights are extinguished and the 339A auto-null circuitry takes over to provide a fast accurate null without tedious operator tuning.
Input Filters (usable on all functions):
Low Pass:
30 kHz - 3 dB point at 30 kHz, + 2.6 kHz, -3 kHz. Provides band limiting required by FCC for proof-of-performance broadcast testing. 80 kHz - 3 dB point at 80 kHz, +7 kHz, -7.9 kHz. Normally used with fundamental frequencies < 20 kHz to reduce the effect of higher frequency noise present in the measured signal.
High Pass:
400 Hz - 3 dB point at 400 Hz, +35 Hz, -40 Hz. Normally used with fundamental frequencies > 1 kHz to reduce the effect of hum components in the input signal.
