VIAVI SPM-16 Selective Level Meter, 10 kHz To 160 MHz (W&G)

The SPM16 Selective Level Meter contains a synthesizer whose special features are low spurious modulation at frequency changeovers and high spectral purity. The SPM16's frequency can be set via a keypad, tuned continuously, or tuned via step and automatic step facilities. The SPM16 is ideal for sweep measurements as its frequency can be varied without causing phase discontinuities. When measuring the total signal level, the microprocessor control ensures that the signal drive range of the level measuring section is optimal. The result of this is high sensitivity, high resolution (0.01 dB) and a large dynamic range for the display (80 dB). Particular frequencies or complete SPM16 settings can be stored, so taking the tedium out of repetitive measurements. These parameters are not lost if there is a power failure. Frequency range: 10kHz to 160MHz Bandwidths: 25 & 400Hz, 1.74, 3.1 & 48kHz Selectivity: >55 dB at 400Hz bandwidth Digital & Analog display Sweep capability Measurement error: <0.3 dB
