- Description
- The Naval Surface Warfare Center, Carderock Division (NSWCCD), code 5600, has been tasked to provide support of support of at sea testing of FSF-1 SEAFIGHTER (X-Craft) has created a requirement for technical and engineering support services. NSWCCD intends to negotiate a competitive procurement with vendors. This is a non-recurring engineering service for purchase of three Model PF-1U-16FA-HP4F/LP4FP-Z-M103, 16-channel Filter Amplifier systems with power supply Control and GUL. The PF-1U-16FA is a 16-channel filter/amplifier and the PF1U-8FA filter/amplifier is an 8-channel both offering a choice of either 4 or -pole low-pass filters or 8-pole band pass filters. Cutoff settings from 1 H to 204.6 kHz are supported. Throw- class filters may operate in either a 93 94 mode for maximally flat pass-band amplitude response with sharp roll-off or in a 93 pulse 94 mode for low phase distortion and optimized transient response. The 93 flat 94 mode provides pass-band characteris tics nearly identical to a Butterworth filter while providing a much sharper roll-off. This mo de is a good choice for applications such as spectral analysis. The 93 pulse 94 mode has time Domain response similar to the Bessel filter yet provides superior amplitude response characteristics. The 93 pulse 94 mode is ideal for time domain applications including transient (shock) measurements and time domain wave form analysis. Programmable pre- and post-filter amplifiers provide an overall gain of 2048. Gain is distributed both before and after the filter to provide protection from large out-of-band energy or transients that could cause clipping before the filter, distorting the data. The post-filter gain has resolution of better than 0.05% to enable system scaling of the outputs to match the full-scale input of the external recording device. Overload detectors alert the user to over-voltage conditions. Precise, automated digital calibration of gain and DC offset are provided. Other features of the PF-1U-FA include a test input for injection of calibration signals into the channel input and a monitor output that allows for convenient monitoring of any channel out put via a single BNC. The system includes an Ethernet remote interface and is supplied with a Graphical User Interface (GUI) for local control. Non-Recurring Engineering for M103 Modification M103 modification replaces the 4 poles HP filter with a single pole HP filter cutoffs between 1 HZ and 100 kHz. Interested person may identify their interest and capability to respond to the requirement or submit proposals. This notice of intent is not request for competitive proposals. This notice of intent is not a request for competitive proposals. However, all responsible sources submitting proposals within 15 days after date of publication of this synopsis will be considered by the Government. A determination by the Government not to compete with this proposed contract based upon responses to this notice is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive pr ocurement. Anticipated award date is on or around 7/24/07. Intereste d parties may forward capabilities statements to the point of contract by no later than 07/25/07
