Gain of SR554

the differential mode. In differential operation the (A) and (B) center conductors carry the signal and shielded preamp ground, and the shields are tied to the SR554 chassis. The (A) and (B) cables should be twisted together to prevent inductive pick-up.

For most experiments it is preferable to use the SR554 in the buffered mode. If the preamplifier is used in the bypass mode, care must be taken to not load the output. The output resistance of the transformer is at least 5 kΩ (for a 0 Ω source) and is typically 10,000 times the input resistance. Therefore, a 50 Ω source impedance will become 500 kΩ. If the instrument that the SR554 is connected to has an input impedance of 1 MΩ, 1/3 of the signal is lost. Any

significant cable capacitance will create a low-pass filter with this output resistance as well, so short cables should always be used.

The actual gain of the SR554 is a function of the source impedance, frequency and the set gain. In the bypass mode (x100), the gain will be affected by loading on the output. The gain is fairly flat over a range of input impedances (<10 Ω) and frequencies (5 Hz-10 kHz). The actual gain can be determined from the amplitude-frequency response curves on page 4. The plot assumes operating the SR554 in the buffered mode or with no loading on the output in the bypassed mode.
