Models in this series
| Model | Type | Channel-to-Channel Isolation | Common Mode Rejection Ratio (CMRR) | Dimensions (W×H×D) |
|---|---|---|---|---|
| TPS2024B | Digital | >= 100:1 at 60 Hz, >= 30:1 at 200 MHz | 1000:1 at 60 Hz, 100:1 at 1 MHz (with TPP0201 passive probes) | 336 mm × 161 mm × 130 mm |
| TPS2012 | Digital | ≥100:1 at 50 MHz | 100:1 at 60 Hz, 20:1 at 50 MHz (with P2220 probe) | 336.0 mm × 161.0 mm × 130.0 mm |
| TPS2014 | DSO | > 100:1 at 100 MHz | 1000:1 at 60 Hz, 100:1 at 1 MHz, 5:1 at 50 MHz (typical, with P2220 probe at 10X) | 336 mm × 161 mm × 130 mm (13.24 in × 6.33 in × 5.10 in) |
| TPS2024 | *misc | ≥ 100:1 at 100 MHz (with equal vertical scale settings) | 100:1 at 60 Hz, 20:1 at 50 MHz (with P2220 probe) | 336 mm × 161 mm × 130 mm |
Channel Isolation and Floating Measurements
The standout feature of the TPS2000 and TPS2000B series is the IsolatedChannel architecture, which provides complete electrical isolation from ground and between channels. This layout is critical when taking measurements where the signals are not referenced to earth ground. For example, the TPS2012, TPS2014, TPS2024, and TPS2024B all offer up to 600 VRMS CAT II or 300 VRMS CAT III of floating voltage protection from the BNC shell to earth ground. This isolation protects the instrument and surrounding circuitry from accidental ground loops and short circuits during testing.
Bandwidth and Channel Configurations
Selecting the proper model depends on the required channel count and bandwidth parameters:
- 100 MHz Models: The TPS2012 provides 2 isolated channels, whereas the TPS2014 provides 4 isolated channels. Both feature a 100 MHz bandwidth. The TPS2014 has a calculated rise time of 3.5 ns.
- 200 MHz Models: The TPS2024 and the TPS2024B offer 4 isolated channels and a higher 200 MHz bandwidth. The TPS2024 features a calculated rise time of 1.75 ns and a time base range extending down to 2.5 ns/div.
Storage and Connectivity Differences
While physical dimensions are uniform across all models—measuring 336 mm wide, 161 mm high, and 130 mm deep with a weight of 2.7 kg without batteries—the data storage interface varies by generation. The legacy TPS2012, TPS2014, and TPS2024 models utilize a CompactFlash (Type I or Type I/II) card slot alongside standard RS-232 and Centronics parallel ports. In contrast, the newer TPS2024B replaces the CompactFlash card slot with a modern front-panel USB 2.0 host port, simplifying data transfer to flash drives while retaining the rear RS-232 and Centronics printer interfaces.
Frequently asked questions
- Can the TPS2000 and TPS2000B series operate without batteries?
- Yes. While designed for portable operation with up to two rechargeable Lithium-Ion batteries, all models can be powered via an AC power supply (90 to 250 V AC or 100 to 240 V AC depending on the specific model).
- Are the input channels isolated from each other on the four-channel models?
- Yes. On the four-channel models, including the TPS2014, TPS2024, and TPS2024B, the IsolatedChannel architecture provides isolation both from channel-to-earth ground and between the BNC shells of individual channels.
