A number of pulsar back-ends are available to Arecibo users. These consist of ``facility'' instruments maintained by NAIC, the WAPP, the Mocks, and PUPPI, while some ``user-owned public-access instruments'' have been generously made available to the community by their owners. The pulsar backends currently accessible by general users are summarized in Table 6.
