We present the observational results from a detailed timing analysis of the black hole candidate Swift J1658.2–4242 during its 2018 outburst with the observations of Hard X-ray Modulation Telescope (Insight-HXMT), Neutron Star Interior Composition Explorer (NICER) and AstroSat in 0.1–250 keV. The evolution of intensity, hardness and integrated fractional root mean square (rms) observed by Insight-HXMT and NICER are presented in this paper. Type-C quasi-periodic oscillations (QPOs) observed by NICER (0.8–3.5 Hz) and Insight-HXMT (1–1.6 Hz) are also reported in this work. The features of the QPOs are analyzed with an energy range of 0.5–50 keV. The relations between QPO frequency and other characteristics such as intensity, hardness and QPO rms are carefully studied. The timing and spectral properties indicate that Swift J1658.2–4242 is a black hole binary system. Besides, the rms spectra of the source calculated from the simultaneous observation of Insight-HXMT, NICER and AstroSat support the Lense-Thirring origin of the QPOs. The relation between QPO phase lag and the centroid frequency of Swift J1658.2–4242 reveals a near zero constant when $<4\text{Hz}$ and a soft phase lag at 6.68 Hz. This independence follows the same trend as the high inclination galactic black hole binaries such as MAXI J1659–152.

我们提供了对黑洞候选者Swift J1658.2–4242在其2018年爆发期间进行详细定时分析的观测结果，包括硬X射线调制望远镜（Insight -HXMT），中子星内部成分探测器（NICER）和AstroSat在0.1-250千电子伏。本文介绍了Insight -HXMT和NICER观察到的强度，硬度和积分均方根（rms）的演变。NICER（0.8–3.5 Hz）和Insight观测到的C型准周期振荡（QPO）-HXMT（1-1.6 Hz）也报告在这项工作中。QPO的特征在0.5–50 keV的能量范围内进行分析。仔细研究了QPO频率与其他特性（例如强度，硬度和QPO rms）之间的关系。时间和频谱特性表明，Swift J1658.2–4242是黑洞二进制系统。此外，通过同时观察Insight -HXMT，NICER和AstroSat计算得出的源均方根光谱支持QPO的Lense-Thirring起源。QPO相位滞后与Swift J1658.2–4242的质心频率之间的关系表明，当$<4\text{赫兹}$和6.68 Hz的软相位滞后。这种独立性遵循与高倾角银河黑洞二进制文件（例如MAXI J1659–152）相同的趋势。
