The A3007B is used in the Data Receiver (A3010). Consult the A3010 manual for pictures of the A3007B.
The A3007C is used in the Data Receiver (A3018). Consult the A3018 manual for pictures of the A3007C.
S3007_1: First page of circuit diagram showing AC-coupled 50-Ω input, RJ-45 connection to the LWDAQ, programmable logic chip, reference oscillator, and 512-KB static RAM. The A3007A and A3007B were shipped originally with different values for the input capacitors and resistors. They had R2=27Ω, C4=2nF, C8=1nF, R3=51Ω.
S3007_2: Second page of circuit diagram showing data clock oscillator, power distribution connectors, and indicator lamp logic. The A3007A does not have U9. On the A3007B U9 is a through-hole part mounted on top of U1. On the A3007C, U9 is a surface-mount part. The remaining circuits on this page are present only in the A3007C.
P3007B: P3007B firmware for logic chip. This firmware has a bug in that causes the A3007B to miss some messages and corrupt others. We recommend upgrading the A3007B with the A3007C firmware, which will work equally well in the A3007B.
P3007C: P3007C firmware for logic chip.
A3010: Manual for the SCT Receiver (A3010), which combines the A3007B and Demodulating Receiver (A3005C). In the manual you will find pictures of the A3007B.
A3018: Manual for the SCT Receiver (A3018), which combines the A3007C, SAW Oscillator (A3016SO), and Demodulating Receiver (A3017A).
