Help with Pulser-Receivers specifications:

Form Factor

	Form Factor:
	Your choices are...
	Bench		Devices are designed to sit atop a bench or desktop.
	Portable / Hand Held		Devices are portable or designed to be operated by hand.
	Printed Circuit Board (PCB)		Devices are printed circuit boards (PCBs) that attach to enclosures or plug directly into computer backplanes.
	Other		Other, not listed, form factors.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Pulser Specifications

	Pulse Voltage Range:		The amplitude of the voltage pulse that is used by the ultrasonic transducer to produce the ultrasonic pulse.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
	Pulse Width Range:		The time of duration of the ultrasonic pulse that is produced.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
	Pulse Repetition Frequency (PRF):		The pulse repetition frequency is the maximum number of pulses per second that the device can produce.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Receiver Specifications

	Voltage Gain Range:		The receiver voltage gain range is expressed in dB. After the ultrasonic pulse is converted to a voltage pulse by a transducer, the receiver can amplify this voltage for subsequent processing.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
	Bandwidth:		This is the 3-dB bandwidth of the receiver.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	High Pass Filters		The receiver has high-pass filters used to attenuate undesirable low frequency signals.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Low Pass Filters		The receiver has low-pass filters used to attenuate undesirable high frequency signals.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Logarithmic Amplifier?		The receiver has a logarithmic amplifier that allows the process of broadband signals.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Other Specifications / Features

	Number of Channels:		The number of channels or probes.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Interfaces:
	Your choices are...
	RS232		RS232 is a serial protocol (connection) used to connect the device to a personal computer for monitoring and control.
	GPIB		GPIB (General Purpose Interface Bus) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. It is also known as IEEE 488 or HPIB, and is electrically equivalent to IEC 625 bus.
	Printer Port		The unit has a port used to connect a printer.
	Other		Other, not listed, interfaces.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Operating Mode:
	Your choices are...
	Pulse / Echo		In pulse-echo mode, the transmitting transducer receives the echoes that are reflected back from the interface.
	Through-transmission		In Through-transmission mode a second transducer is used to receive and convert the ultrasonic pulse.
	Other		Other, not specified, operating modes such as External Pulser Mode.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
