- Description
- The purpose of this amendment is to answer questions posed by potential offerors and to provide for an extension in the due date for the receipt of proposals. The questions and answers are as follows: 1. Paragraph 3.1.3 (c) of the specifications indicates that data resolution shall be adjustable in the12 bit to 32 bit range. What do you anticipate the mix of channels to be among 12 and 32 bit signals? Specifically, do you anticipate a high number of 32 bit signals being monitored? Clock resolution should be 32 bit. Instrumentation signal imput should be in the 12 to 24 bit range. 2. The specification does not specify the quantity of specific channel types that are required in each Node Room. For example, Node Room 1 needs 100 channels. For example, is that (30) +/- 5mVDC channels and (30) +/- 30 VDC and (40) 0-20mA channels? 70% of each node room capacity must be dissimilar metal thermocouple compatible (Type K). The remaining 30% should be capable of handing copper/copper instrumentation wiring with output voltages in the +/- 5m VDC and +/- 30 VDC range. 3. Paragraph 3.1.3 (e) of the specifications requires built in conversion circuitry. What part of this application requires 32-bit analog to digital conversion (ADC)? a. Typical applications for industrial controls utilize 12-bit ADCs quite adequately. This is roughly 3 5 digits of resolution in decimal representation. Sensitive measurements often require 16-bit resolution, or 5 digits, to more accurately represent measured voltages. Laboratory grade measurements sometimes need 24 bits of resolution to sample voltages with 7.5 digits of accuracy. Is there really a need to sample voltages with 9.5 digits of resolution with a 32 bit ADC stage for this procurement? b. Is this a misprint? The synchronization clock requires 32-bit resolution. Signal inputs from instrumentation require A/D conversion resolution in the 12-bit to 24-bit range. 4. Software - What is the requirement for Data Acquisition Software? Please detail. Is custom data acquisition and software interfaces required? If custom software is not required, how will acceptance testing be performed? Can you please describe further the requirements under licensed software, ii, iii, iv? What are remote module data acquisition software requirements? What data acquisition capabilities on server and remote real time system? Data acquisition software should be of the same type and capability as found in Labview. The Labview package is acceptable. By licensed software, NRL means licensed copies of all software such that the software manufacturers will provide technical support if needed. 5. For clarification, should each remote data acquisition module include a UPS backup? What is the housing / cabinet requirements for the remote modules and UPS if required? Sufficient UPS back-up capability, for each node room, for however many remote acquisition modules are proposed per node room is required to supply at least 30 minutes of emergency power. If this can be achieved with one UPS unit per node room, that is acceptable. Offerors may propose their own cabinet architecture, but should keep in mind that the UPS units may perform in node rooms that are non-airconditioned, humid, and possibly dirty. 6. Please clarify – do you really mean a 32-bit data acquisition resolution. This far exceeds most commercial and Department of Defense standards? If not, please state what is required resolution. See above answer. The synchronization clock requires 32-bit resolution. Signal inputs from instrumentation require A/D conversion resolution in the 12-bit to 24-bit range. 7. NRL’s Specification states that un-airconditioned spaces can reach temperatures in excess of100°C, how much in excess? Temperatures in the un-airconditioned node rooms can get up to 120 degrees F in the summer. The equipment must perform accur NOTE: THIS NOTICE WAS NOT POSTED TO FEDBIZOPPS ON THE DATE INDICATED IN THE NOTICE ITSELF (07-APR-2006); HOWEVER, IT DID APPEAR IN THE FEDBIZOPPS FTP FEED ON THIS DATE.
