See option description for details. Data storage functions Built-in 3.5 in., 1.44-Mbyte flexible disk also supports 720-KByte disks, and 2 Mbyte NVRAM disk. Both MS-DOS® and HP-LIF formats are available. Data can be formatted as either ASCII or binary (SDF). The 35670A provides storage and recall from the internal disk, internal RAM disk, internal NVRAM disk, or external GPIB disk for any of the following information: Instrument setup states User-math Time capture buffers Waterfall display data Data tables Trace data Limit data Agilent Instrument BASIC Programs Curve fit/synthesis tables Input channels Manual range Up-only auto range Up/down auto range Anti-alias filters On/Off AC or DC coupling LED half range and overload indicators Floating or grounded A-weight filters On/Off Transducer power supplies (4 ma constant current) Frequency 20 spans from 195 mHz to 102.4 kHz (1 channel mode) 20 spans from 98 mHz to 51.2 kHz (2 channel mode) Digital zoom with 244 µHz resolution throughout the 102.4 kHz frequency bands.

When the internal cooling fan has been turned OFF, specifications apply within 5 minutes of the last self-calibration. All specifications are with 400 line frequency resolution and with anti-alias filters enabled unless stated otherwise.
