DESCRIPTION
The model 7070 is a Wilkinson-type Analog-to-Digital Converter with a 100 MHz clock rate. The 7070 is ideally suited for applications in nuclear- and X-ray Spectroscopy. The upper- and lower-level discriminator has a separate output on the rear panel.
SPECIFICATION INPUTS (front panel) Signal Input: BNC-Connector accepts +25mV to +8V (standard / +10V optional) linear pulses, Zin = 1k Ohm, risetime: > 100ns to 100µs, fall time: 200ns to 100µs, 0.5µs flat top width, dc coupled. Gate: BNC-Connector accepts positive TTL
OUTPUTS (rear panel) Data 13 bit binary data lines and data transfer commands, Amphenol D-Sub-connector.
SCA-output: BNC-connector, TTL pulse approx. 0.5µs duration. One output pulse for each input signal that falls between the ULD and LLD setting.
INDICATORS DEADTIME: LED-bar indicates activity of the ADC. Range 0 to 100% deadtime
Front Panel Controls Offset: Digital Offset, range 0 to 8k in steps of 256 channels.
Conversion Gain: Six position rotary switch selects quantisation of 256, 512, 1k, 2k, 4k, or 8k channels for full scale input. Data is compressed to 8, 9, 10, 11, 12 and 13 bits.
LLD: Precision potentiometer sets the lower level discriminator.
ULD: Precision potentiometer sets the upper level discriminator.
Zero: Precision potentiometer sets the "zero" level from 0 to +/-200mV.
Coinc - /Coinc: Toggle switch selects coincidence or anticoincidence mode. |
