GeoPulse Profiler
Specification
Transmitter - Model
5430A
|
Output: |
10
kW with 0.75% duty cycle, continuously adjustable. 2 to 12 kHz,
continuously adjustable. Short circuit proof. Impedance matched. |
| Pulse Cycles: |
1, 2, 4, 8, 16, or 32 cycles of the frequency
selected.
The transmitted output pulse will be phase coherent within 22.5°. |
| Key: |
External: |
2 to 12 V pulse, either + or – leading edge
triggered. Maximum width 50ms to eliminate double triggering. Transformer
isolated. |
| |
Internal: |
Set by internal potentiometer, 1 to 10pps, uncalibrated.
|
| Output to Receiver
or digital sonar processing system: |
Transformer isolated. Frequency response flat
between approximately 1 kHz and 20 kHz. Two modes of operation:
A: Flat gain –0 dB gain
B: Short range TVG -20 dB (10:1) of attenuation during transmit pulse and a
–20 dB to 0dB ramp within 15ms after end of transmit signal. |

Receiver Model 5210A
| Amplifier: |
Differential common mode rejection: 100dB at 60Hz. Sensitivity 30µV RMS in, produces 1V RMS out at 90dB total
gain with TVG. |
| Signal to Noise: |
20dB at 100dB gain 1kHz centre frequency and 1kHz bandwidth. |
| Coarse Gain: |
40dB maximum. |
| Fine Gain: |
0-30dB in 3dB increments. |
| Filter: |
Low pass and high pass, active type,
maximally flat, 24dB/octave minimum roll-off, 0 gain, 0.02kHz to 15kHz
adjustable in ½ octave increments. Knobs interlock to prevent overlap. |
| TVG: |
Dynamic range: 30dB.
Rate: approximately flat to 30dB in 14 ms.
Manual delay: vernier adjust from 1 to 14ms with multiplier of x 1, x 10, x 100
and internal select of x 1000. |
| AGC: |
Attack adjustable from 330µs to 330ms.
Decay: adjustable from 330µs to 330ms.
Range: 20dB. |
| Power: |
115/230VAC ±10% (internal switch selectable),
