- Description
- *** 16 March 2015 *** This solicitation is modified to extend the due date for proposals to 27 April 2015, 2 pm EDT. There have also been some questions regarding the purchase description. The questions along with the engineer's response is provided below. Question: 4.4. User Interface: The Distortion Analyzer shall maximize the use of electronically programmable interfaced components. The format of the interface shall be IEEE 488.2 Standard. The Distortion Analyzer shall also make use of all programmable components to perform automated measurements via a government owned programmable system controller. Can you tell me what the GPIB controller will be used for in this application as it is not defined in the PD. It appears from section 4.4 of the PD that more features are desired than are clearly defined. Response: The specifics on how we will automate the distortion analyzer are irrelevant. Paragraph 4.4 is only requiring the distortion analyzer to have an IEEE 488.2 interface, or GPIB connector, that will allow us to automate the instrument. The second sentence requires that the contractor maximize the instruments ability to be automated, meaning that anything that can and should be done automatically (measurements, functions, etc.) be included. Question: What was the original make and model of the instrument that you are replacing? Response: A combination of the Hewlett Packard 334A and 8903A Questions: 1. Paragraph 3.3 Voltage Input a. What is meant by this specification? 1. Is the 0.3 to 200V a peak, peak-to-peak or rms voltage? 2. Is this an input voltage that can be ±3% above and below the 0.3 to 200V? 3. Is this a voltmeter mode where the distortion analyzer can measure voltage to with a ±3% accuracy full scale? 2. Paragraph 3.4 Distortion Levels a. Do you really want the distortion analyzer to measure 100% distortion level? Our distortion analyzer measures to the 10th harmonic and 20% distortion max. 3. Paragraph 3.5 Distortion Measurement Accuracy a. Do you really need 7 full scale distortion ranges? b. Do you want these ranges to be switch selectable via the front panel? c. Our instrument is totally automatic with auto-ranging and auto-leveling which basically makes it hands-free operation; would this be acceptable? 4. Paragraph 3.6 Input Impedance a. Can you live with an input impedance of 110k ohms in parallel with a 100pF? Responses: 1. Paragraph 3.3 Voltage Input a. This is the input voltage where the Distortion Analyzer must be capable of measuring distortion. 1. RMS 2. Yes 3. The Distortion Analyzer should be capable of measuring the voltage to determine if the input voltage is within the +/-3% of full scale. 2. Paragraph 3.4 Distortion Levels a. Yes, the requirement is to measure 100% distortion levels. 3. Paragraph 3.5 Distortion Measurement Accuracy a. The accuracy is based on the 7 full scale ranges described in 3.5. As long as the Distortion Analyzer can meet these accuracies, ranges can be varied. b. There are no requirements on how ranges are selected/changed. c. There are no requirements on how ranges are selected/changed. 4. Paragraph 3.6 Input Impedance a. No.
